Reference

This module implements functions to create your own fabulous basis functions, primarily for the analysis of galaxy redshift surveys.

The abstract type CryoFaB defines a common interface for the bases defined in this module.

        δnlm = cfb \ δθϕr[:]

calcnumgalsper_cell(rθϕ, cfb::CryoFaB)

Calculate the number of galaxies in rθϕ in each pixel or voxel in the survey that cfb can act on. The radial coordinates are in rθϕ[1,:], etc.

estimatedensitycontrast(rθϕ, cfb::CryoFaB)

Estimate the density contrast from the galaxy positions in rθϕ.
