Code of Conduct & Commitment to Maintain Package

• I agree to abide by pyOpenSci's Code of Conduct during the review process and in maintaining my package after should it be accepted.
• I have read and will commit to package maintenance after the review as per the pyOpenSci Policies Guidelines.

Description

ZodiPy is a new Python tool for modelling the zodiacal emission seen by an arbitrary Solar System observer, which can be used for removal of both thermal emission and scattered sunlight from interplanetary dust in astrophysical data. One of our main goals with ZodiPy is to make zodiacal emission simulations more accessible by providing the community with a simple Python interface to existing models. We recently published a paper on ZodiPy (which has also been accepted to A&A) where we describe in more detail modelling of zodiacal emission and the approach taken by ZodiPy.

ZodiPy uses Astropy both in the public API and internally. When using one of the methods provided to simulate the zodiacal emission, the user needs to use Quantity and Time types in input arguments such as frequency/wavelength, angles on the sky, and the time of observation. Internally, the Time object is used to compute the heliocentric ecliptic position of the Earth and the observer with the SkyCoord and other functionality in astropy.coordinates.

Scope

• Please indicate which category or categories.
  Check out our package scope page to learn more about our
  scope. (If you are unsure of which category you fit, we suggest you make a pre-submission inquiry):

  • Data retrieval
  • Data extraction
  • Data processing/munging
  • Data deposition
  • Data validation and testing
  • Data visualization¹
  • Workflow automation
  • Citation management and bibliometrics
  • Scientific software wrappers
  • Database interoperability

ZodiPy was already proposed and reviewed as an Astropy Affiliated package before the recent partnership between Astropy and pyOpenSci in APE22, so I am resubmitting the proposal as is here.

Domain Specific

• Geospatial
• Education

Community Partnerships

If your package is associated with an
existing community please check below:

• Astropy: Link coming soon to standards
• Pangeo: My package adheres to the Pangeo standards listed in the pyOpenSci peer review guidebook

• For all submissions, explain how the and why the package falls under the categories you indicated above. In your explanation, please address the following points (briefly, 1-2 sentences for each):

  • Who is the target audience and what are scientific applications of this package?

    • The target audience is astronomers and cosmologists who work with sky observations all the way from the optical to CMB-frequencies. The scientific application of the this package is to provide the astronomer with and open source tool to create simulated timestreams, snapshots, or maps of the zodiacal light as seen from earth or any other arbitrary solar system observer. This allows existing experiments with data contaminated by zodiacal light to model and remove the light from their data, and future experiments can, and some already has (Nancy Grace Roman Space Telescope) use ZodiPy to make forecasts and simulations.

  • Are there other Python packages that accomplish the same thing? If so, how does yours differ?

    • There exists a few zodiacal light tools but these are all experiment specific and can only be used to model the zodiacal light that was observed in their data. ZodiPy is as far as i know the only Python package that allows for arbitrary solar system observers to make zodiacal light simulations. ZodiPy is also extendible and can easily be updated with new improvements to zodiacal light models and even used to fit new models.

  • If you made a pre-submission enquiry, please paste the link to the corresponding issue, forum post, or other discussion, or @tag the editor you contacted:

Editor comments

Hello there and welcome to the pyOpenSci universe (apologies for the bad pun 😂🌟)! We're happy you're here. I've done a quick overview of the zodipy package, and you are in great shape! There are a few things we will need before we start with your review:

1. Please add a CODE_OF_CONDUCT.md to the root of your repository. For more information, pyOpenSci's packaging guide has some examples and information on CoC files.
2. Please add a CONTRIBUTING.md to the root of your repository. For more information, pyOpenSci's packaging guide has some templates and information on CONTRIBUTING files.
3. I'll also nudge each maintainer (so, @MetinSa @dncnwtts) to fill out our onboarding survey.

Let us know when you've made these updates. I'll also use this message to introduce your editor-- @dhomeier will be helping you all through the review process 🎉 Thanks for taking on this role Derek!

[MetinSa]

Hi! 👋

I have now added a CODE_OF_CONDUCT.md and a CONTRIBUTING.md to the repository aswell as having filled out the survey. I also added @hermda02 as a maintainer of the project.

Package Review

Please check off boxes as applicable, and elaborate in comments below. Your review is not limited to these topics, as described in the reviewer guide

• As the reviewer I confirm that there are no conflicts of interest for me to review this work (If you are unsure whether you are in conflict, please speak to your editor before starting your review).

Documentation

The package includes all the following forms of documentation:

• A statement of need clearly stating problems the software is designed to solve and its target audience in README.
• Installation instructions: for the development version of the package and any non-standard dependencies in README. (Reviewer note: DOC: No dev install instructions or mention of non-standard dependencies in README Cosmoglobe/zodipy#4 and poetry install downgrades numpy and fails Cosmoglobe/zodipy#10)
• Vignette(s) demonstrating major functionality that runs successfully locally.
• Function Documentation: for all user-facing functions.
• Examples for all user-facing functions.
• Community guidelines including contribution guidelines in the README or CONTRIBUTING.
• Metadata including author(s), author e-mail(s), a url, and any other relevant metadata e.g., in a pyproject.toml file or elsewhere.

Readme file requirements
The package meets the readme requirements below:

• Package has a README.md file in the root directory.

The README should include, from top to bottom:

• The package name
• Badges for:
  • Continuous integration and test coverage,
  • Docs building (if you have a documentation website) (Reviewer note: DOC: Missing badge from gh-pages deployment workflow Cosmoglobe/zodipy#5),
  • A repostatus.org badge (Reviewer note: DOC: Missing badge for repostatus.org Cosmoglobe/zodipy#6),
  • Python versions supported (Reviewer note: DOC: missing badge for Python versions supported Cosmoglobe/zodipy#7),
  • Current package version (on PyPI / Conda).

NOTE: If the README has many more badges, you might want to consider using a table for badges: see this example. Such a table should be more wide than high. (Note that the a badge for pyOpenSci peer-review will be provided upon acceptance.)

• Short description of package goals.
• Package installation instructions
• Any additional setup required to use the package (authentication tokens, etc.) (Reviewer note: N/A)
• Descriptive links to all vignettes. If the package is small, there may only be a need for one vignette which could be placed in the README.md file.
  • Brief demonstration of package usage (as it makes sense - links to vignettes could also suffice here if package description is clear)
• Link to your documentation website.
• If applicable, how the package compares to other similar packages and/or how it relates to other packages in the scientific ecosystem. (Reviewer note: I do not know enough about zodiacal light community to check off this one.)
• Citation information

Usability

Reviewers are encouraged to submit suggestions (or pull requests) that will improve the usability of the package as a whole.
Package structure should follow general community best-practices. In general please consider whether:

• Package documentation is clear and easy to find and use.
• The need for the package is clear
• All functions have documentation and associated examples for use
• The package is easy to install

Functionality

• Installation: Installation succeeds as documented.
• Functionality: Any functional claims of the software been confirmed.
• Performance: Any performance claims of the software been confirmed.
• Automated tests:
  • All tests pass on the reviewer's local machine for the package version submitted by the author. Ideally this should be a tagged version making it easy for reviewers to install.
  • Tests cover essential functions of the package and a reasonable range of inputs and conditions.
• Continuous Integration: Has continuous integration setup (We suggest using Github actions but any CI platform is acceptable for review)
• Packaging guidelines: The package conforms to the pyOpenSci packaging guidelines. (Reviewer note: Not using src layout but should not matter.)
  A few notable highlights to look at:
  • Package supports modern versions of Python and not End of life versions.
  • Code format is standard throughout package and follows PEP 8 guidelines (CI tests for linting pass)

For packages also submitting to JOSS

• The package has an obvious research application according to JOSS's definition in their submission requirements.

Note: Be sure to check this carefully, as JOSS's submission requirements and scope differ from pyOpenSci's in terms of what types of packages are accepted.

The package contains a paper.md matching JOSS's requirements with:

• A short summary describing the high-level functionality of the software
• Authors: A list of authors with their affiliations
• A statement of need clearly stating problems the software is designed to solve and its target audience.
• References: With DOIs for all those that have one (e.g. papers, datasets, software).

Final approval (post-review)

• The author has responded to my review and made changes to my satisfaction. I recommend approving this package.

Estimated hours spent reviewing: 4

Astropy-specific

• Relevance to astronomy/astrophysics:
  • Out of scope: Not useful for astronomers, or specific to one project/collaboration. (This is a basis for rejection.)
  • Specialized package: Useful to astronomers working in a very specific domain/field, or with a specific telescope instrument and usable not just by a single collaboration but any astronomers within that domain. Packages such as sncosmo fall into this category.
  • General package: Package that is useful for astronomers across more than a single field/instrument/telescope. Packages such as astroquery or astroplan fall into this category.
• Integration with Astropy ecosystem:
  • No integration: Does not use Astropy or other Astropy Affiliated packages anywhere where it should be possible, and/or uses other libraries instead, or unnecessarily duplicates functionality found in Astropy or other Astropy Affiliated packages. (This is a basis for rejection.)
  • Partial integration: Makes an effort to use Astropy or other Astropy Affiliated packages in places, but still has other places where this could be done.
  • Good integration: Uses Astropy or other Astropy Affiliated packages wherever possible. Where not, there are good reasons not to.
    For specific actionable items, reviewer or editor are free to open issues on the package repository directly and link them

Review Comments

I skipped the JOSS section because I don't see a paper.md and so assume this package isn't asking for JOSS listing also.

2024-04-16: I updated the JOSS section but left References unchecked because paper.md has empty section for that part.

This package is already in Astropy's pre-APE 22 legacy listing over at https://www.astropy.org/affiliated/legacy.html via astropy/astropy.github.com#495 .

[MetinSa]

I'm sorry, I had forgotten about the JOSS section but would very much like a JOSS listing. I will start working on a paper.md.
