[SPRINT] Galcheat

Galcheat

Galcheat is a lightweight package containing useful parameters from main galaxy surveys (with units).

The purpose of this sprint is to bring people together to ensure the survey information in galcheat is correct so that it can start being helpful to others in the collaboration.

Contacts: @aboucaud, @ismael-mendoza
Day/Time: 8a - 12p EST
Main communication channel: #blending_toolkit
GitHub repo: https://github.com/aboucaud/galcheat
Zoom: Join us in the #blending_toolkit slack channel for discussions and connection info (zoom room is pinned).

Goals and deliverable

Deliverables:

• Ensuring units are consistent for some of the most obscure quantities (e.g. extinction)
• Ensure function from magnitude to fluxes is correct (Implement utility functions purely related to survey and filter numbers surveycodex#24)
• Test current API and giving feedback if needed
• Implemented surveys should have references for each number used.

Resources and skills needed

Anyone with experience in python is welcome!

We would be especially grateful if people with expertise on survey simulations (e.g. how to go from magnitude to fluxes) join and can help us figure out consistent units!

Detailed description

The goal of this project is to provide a Python library with minimal dependencies that centralises galaxy survey properties with adequate reference. Such information tends to be scattered in many places or is often copy/pasted without all of the relevant information like units or sources.

This project was developed as part of the work done by the BlendingToolKit (soon to be) Topical Team. Most of the information from the different surveys was originally in WeakLensingDeblending.

Help is specifically needed for the following issues

• add references for Rubin parameters surveycodex#25
• add references for HSC parameters surveycodex#26
• add references for Euclid parameters surveycodex#27
• add references for CFHT parameters surveycodex#28

I just updated the CONTRIBUTING document to help participants submit their pull requests
