Simple Binning Suite

The simple binning suite includes modules for peforming a simple binning search of stellar overdensities in DES &c data, compiling a candidate list from the results of the search, and producing diagnostic plots from a candidate list.

This code has been adapted from Keith Bechtol's original simple binning program to be more modular and ready-to-use for future searches.

Maintained by Sidney Mau.

Dependencies

This program uses the following:

python; numpy, scipy, healpy, astropy, matplotlib, fitsio

ugali, batchtools (for farming)

and some others that I've forgotten to write down.

Configuration and use

config.yaml handles most of the setup and can be modified according to use. You will need to modify the value for the simple_dir key to be the path to your simple folder that contains these source files.

You will need to create a directory such as simple_run/. Copy config.yaml into simple_run/; this will let the the scripts know where to source the config info from as well as where to write the output. If you have fracdet or maglim files, those should also be copied or linked here; specify their filepaths in config.yaml.

To run the simple binning search, run farm_simple.py in simple_run/. This will run search_algorithm.py over the given data set and write the output to results_dir/, logging each job in results_dir/log_dir. The results can then be compiled into a candidate list by running make_list.py from simple_run/ (this is saved as a .npy file).

To produce plots from a candidate list, run farm_plots.py in simple_run/. The output will be written to save_dir/ with logs in save_dir/log_dir/.

Notes

By default, farm_plots.py will only produce plots for hotspots with statistical significance greater than 5.5 sigma. This threshold has intentionally chosen to be low (such that investigations can be made of very low-significance hotsposts and candidates) but also to minimize junk.
