f3

Full Frame Fotometry package for interacting with and measuring photometry for targets observed in the Kepler Full Frame Images

You can read the documentation at: f3.readthedocs.io.

Installation

Start by installing the dependencies:

  1. numpy
  2. matplotlib
  3. scipy
  4. astropy
  5. kplr (https://github.com/dfm/kplr) (The version pip will get you is insufficent, grab the one on github)
  6. mahotas (http://mahotas.readthedocs.io/en/latest/#) (pip will install this for you along with f3)

Running “pip install f3” or cloning this repository and running setup.py should then enable you to run the code.

Get the data

To download the Kepler full frame images, run:

wget -r -nH -nd -np -R index.html -e robots=off https://archive.stsci.edu/pub/kepler/ffi/

Note: this is 44gb worth of data!

f3 will look for this in the “ffidata” subdirectory inside your working directory, but this can be changed in an argument when you initialize your object.

Use the code

There is a jupyter notebook in this directory which provides an example use case for this package.
