# 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 Galactic emission
# components, which currently includes the following components:
# - synchrotron
# - freefree
# - snr
#
# NOTE:
# - The input templates for simulations should be HEALPix full-sky maps.
# - The input catalog should be in CSV format.
