Function Documentation#

double trv::calc_powspec_normalisation_from_meshes(trv::ParticleCatalogue &particles_data, trv::ParticleCatalogue &particles_rand, trv::ParameterSet &params, double alpha)#

Calculate power spectrum normalisation from mixed meshes.

This normalisation convention is used for paired survey-type catalogues only, where the two meshes come from separate data- and random-source particle catalogues.

documentation.

Parameters

  • particles_data – Data-source particle catalogue.

  • particles_rand – Random-source particle catalogue.

  • params – Parameter set.

  • alpha – Alpha contrast.

Returns

Power spectrum normalisation factor.
