# Configurations for "fg21sim" # -*- mode: conf -*- # # Syntax: `ConfigObj`, https://github.com/DiffSK/configobj # # There are various configuration options that specify the input data # and/or templates required by the simulations, the properties of the input # data, the output products, as well as some parameters affecting the # simulation behaviors. # # This file contains the options corresponding the extragalactic emission # components, which currently includes the following components: # - clusters: halos # - pointsources [extragalactic] # Extended emissions from the clusters of galaxies # The configurations in this ``[[clusters]]`` section may also be # used by the following ``[[halos]]`` section.
