cosmo_utils

Utilities for working with catalogs (mostly Raygal lightcones) and perform basic cosmology computations such as distances, volumes, growth factor, growth rate, P(k)-xi etc...

• Catalog loading/filtering and filename metadata parsing
• Corrfunc pair-count filename decoding and retrieval
• Cosmology helpers (growth, volume, P(k) I/O)
• Filters and special functions

Package layout

• cosmo_utils.utils — I/O helpers (JSON, PK), path utilities, Corrfunc filename parsing, result writers
• cosmo_utils.cosmology — cosmology calculations (see cosmology.Cosmology)
• cosmo_utils.filters_et_functions — Special functions and useful filters
• cosmo_utils.catalogs — catalog retrieval, filtering, sampling, and small plotting helpers

Configuration files (JSON) are expected under:

• src/cosmo_utils/config
