APEX_CMZ_H2CO

Data: On the Dataverse

Installation

We recommend using conda to install the basic required packages: astropy, scipy, numpy, matplotlib.

A few packages will need to be installed that are not on conda. Most of these exist on pip, but not all:

pip install FITS_tools, sdpy, astroquery, pyspeckit, spectral_cube, agpy
pip install https://github.com/keflavich/mpl_plot_templates/archive/master.zip
pip install https://github.com/keflavich/image_tools/archive/master.zip

The install script should take care of other dependencies:

python setup.py install

Description

A paper, reduction and analysis code, and observing scripts and logs from the 2013-2014 APEX survey of 218 GHz H2CO in the CMZ.

The MPI and ESO observing scripts are in their respective directories. A few "emission-free" off positions were selected based on the Dame 2001 data. Run off_position_selection.py to generate a diagram demonstrating this (it will automatically download the necessary data). One can also demonstrate that these are relatively emission-free using the Bell Labs 7m 12CO 1-0 data, with apologies for the FITS header.

The off positions are green X's in this map, with two additional blue points identified by Jens Kauffmann and Walker Lu: Imgur

Note that Jens' point reportedly showed some signal around SiO, while Walker's did not.

Here are the target regions colored by their association with the selected off position: Imgur

Pipeline

An example run of the pipeline is hosted on gist. This is pretty outdated but kept for posterity.
