MCSED Command-Line Options

The main script is run_mcsed_fit.py. Control options for MCSED can either be entered on the command line, or stated in the configuration file config.py. To view all the command line options, open a terminal in the MCSED directory and issue:

python run_mcsed_fit.py -h

You will see a drop down menu of all the available input arguments. This menu is reproduced below.

usage: -h [-h] [-f FILENAME] [-o OUTPUT_FILENAME] [-p] [-t] [-tf TEST_FIELD]

[-no NOBJECTS] [-s SSP] [-i ISOCHRONE] [-sfh SFH] [-dl DUST_LAW]

[-de DUST_EM] [-aeb] [-z METALLICITY] [-nw NWALKERS] [-ns NSTEPS]

[-lu LOGU] [-ism ISM_CORRECT_COORDS] [-igm]

Optional Arguments:

-h, --help: show this help message and exit

-f FILENAME, --filename FILENAME: File to be read for galaxy data

-o OUTPUT_FILENAME, --output_filename OUTPUT_FILENAME: Output filename for given run

-p, --parallel: Running in parallel?

-t, --test: Test mode with mock galaxies

-tf TEST_FIELD, --test_field TEST_FIELD: Test filters will match the given field

-no NOBJECTS, --nobjects NOBJECTS: Number of test objects

-s SSP, --ssp SSP: SSP (single stellar population) Models, default fsps

-i ISOCHRONE, --isochrone ISOCHRONE: Isochrone for SSP model, e.g. padova

-sfh SFH, --sfh SFH: Star formation history, e.g. constant

-dl DUST_LAW, --dust_law DUST_LAW: Dust law, e.g. calzetti

-de, --dust_em: Dust emission class, e.g., DL07

-aeb, --assume_energy_balance: If true, normalization of dust IR emission based on attenuation amount

-z METALLICITY, --metallicity METALLICITY: Fixed metallicity for SSP models (0.019 is solar), False if free parameter

-nw NWALKERS, --nwalkers NWALKERS: Number of walkers for EMCEE

-ns NSTEPS, --nsteps NSTEPS: Number of steps for EMCEE

-lu LOGU, --logU LOGU: Ionization Parameter for nebular gas

-ism, --ISM_correct_coords: If a coordinate system is given, MW dust correction will be performed

-igm, --IGM_correct: If selected, Madau statistical IGM correction will be done (affecting wavelengths up to rest-frame Ly\(\alpha\))
