# Example configuration file for "fg21sim" # -*- mode: conf -*- # # Syntax: `ConfigObj`, https://github.com/DiffSK/configobj # # This file contains all the configuration options accepted by "fg21sim", # which control the simulation parameters, inputs data and outputs products, # as well as some general behaviors. # # Some options already have a default value been set in the bundled # configuration specifications, which will be further described below with # their default values and be commented out. # # However, there is not a sensible default value for other options, # therefore, users should explicitly set their values before carrying out # the simulations. These options are also explained in details below, and # marked with "REQUIRED". # # NOTE: # - The input templates for simulations should be HEALPix full-sky maps. # - The input catalog should be in CSV format. # Common/general configurations for the simulation [common] # HEALPix Nside value, i.e., pixel resolution # NOTE: also update "lmax" below. #nside = 1024 # Range of multipole monents (l) of the angular power spectrum. # The power spectrum will be cut off to a constant for multipole l < lmin. # Generally, lmax = 3 * nside -
