Tomographic GLASS mock generation #213

Description

@sachaguer

Goal

Upgrade the existing code to generate GLASS mocks with tomography. This is a high priority step as being able to generate UNIONS-like mock will allow to test all the downstream sp_valiation tasks such as data vector measurements with tomography, the conversion to CosmoSIS-like data vectors, and inference.

To do

The task is relatively elementary as GLASS already allows to handle tomography. What needs to be implemented is a nice API/config to provide the inputs to the GLASS mocks and tests to the scripts.

Input

  • Redshift distribution 🟢
  • Number density and shape noise for each redshift bin 🟢
  • A mask 🟢
  • Cosmology 👍

    The pushed version contains an updated script to generate GLASS mocks with tomography.

    The version is being tested. I upgraded the interface to read config files, which are now the main argument to the CLI.

    To do

    • Allow for different shape noise and density per redshift bin.
    • Add an option to run a first validation check at the end of the simulation production. (computation of shape noise + number density).
    • Provide tests of the script on the scratch.
