Tiny library of galaxy surveys most useful parameters (with units)

Galaxy Surveys cheatsheet

Tiny package containing useful parameters from main galaxy surveys (with units)

The goal of this project is to provide a centralised library containing galaxy survey properties often required for simulations. Such information tends to be scattered in many places or is often copy/pasted without all of the relevant information like units or sources.

Setup

1. Create a virtual environment

   python -m venv venv
   source venv/bin/activate
   

2. Install the library with its requirements

   python -m pip install git+https://github.com/aboucaud/galcheat
   

3. Run the demo = print the available surveys and associated filters

   python -m galcheat
   

API

from galcheat import survey_info

# Available surveys
print(list(survey_info.keys()))

# Rubin U band PSF FWHM
Rubin = survey_info["Rubin"]
fwhm = Rubin.filters.u.psf_fwhm  # Quantity object with units
print(fwhm)

# Retrieve the value in the original units
print(fwhm.value)

# Or convert to other units
import astropy.units as u
print(fwhm.to_value(u.arcmin))
