rail.interactive.creation.engines.fsps_photometry_creator module

rail.interactive.creation.engines.fsps_photometry_creator.fsps_photometry_creator(**kwargs)

Derived class of Creator that generate synthetic photometric fsps_default_data from the rest-frame SED model generated with the FSPSSedModeler class. The user is required to provide galaxy redshifts and filter information in an .npy format for the code to run. The restframe SEDs are stored in a pickle file or passed as ModelHandle. Details of what each file should contain are explicited in config_options. The output is a Fits table containing magnitudes.

—

Creates observed magnitudes for the population of galaxies and stores them into an Hdf5Handle.

This function was generated from the function rail.creation.engines.fsps_photometry_creator.FSPSPhotometryCreator.sample

Parameters:

  • restframe_sed_key (str, optional) – Rest-frame SED keyword name of the hdf5 dataset containing rest-frame SEDs Default: restframe_seds

  • restframe_wave_key (str, optional) – Rest-frame wavelengths keyword name of thehdf5 dataset containing rest-frame SEDs Default: wavelength

  • apparent_mags_key (str, optional) – Apparent magnitudes keyword name of the output hdf5 dataset Default: apparent_mags

  • filter_folder (str, optional) – Folder containing filter transmissions Default: rail/examples_data/creation_data/data/fsps_default_data/filters

  • instrument_name (str, optional) – Instrument name as prefix to filter transmission files Default: lsst

  • wavebands (list, optional) – Comma-separated list of wavebands Default: [‘u’, ‘g’, ‘r’, ‘i’, ‘z’, ‘y’]

  • filter_wave_key (str, optional) – Default: wave

  • filter_transm_key (str, optional) – Default: transmission

  • w0 (float, optional) – Dark energy equation-of-state parameter at current time Default: -1

  • wa (float, optional) – Slope dark energy equation-of-state evolution with scale factor Default: 0.0

  • h (float, optional) – Dimensionless hubble constant Default: 0.7

  • use_planck_cosmology (bool, optional) – True to overwrite the cosmological parameters to their Planck2015 values Default: False

  • physical_units (bool, optional) – False (True) for rest-frame spectra in units ofLsun/Hz (erg/s/Hz) Default: False

Returns:

Hdf5Handle storing the apparent magnitudes and redshifts of galaxies.

Return type:

dict

Notes

This method puts seed into the stage configuration data, which makes them available to other methods. It then calls the run method. Finally, the Hdf5Handle associated to the output tag is returned.
