Extracts the path to the synthetic catalogues.

Parameters:

catl_kind : {‘data’, ‘mocks’} str, optional

Type of catalogue to use. This variable is set to data by default.

Options:
  • data : catalogues come from SDSS real catalogue
  • mocks : catalogue come from SDSS mock catalogues

catl_type : {‘mr’, ‘mstar’} str, optional

Type of catalogue to use. It shows which abundance matching method was used for the CLF when assigning halo masses. This variable is set to ‘mr’ by default.

Options:
  • mr : Uses r-band absolute magnitude
  • mstar : Uses stellar masses

sample_s : {‘19’, ‘20’, ‘21’} str, optional

Volume-limited sample to use. This variable is set to ‘19’ by default.

Options:
  • ‘19’ : Uses the Mr19 volume-limited sample, i.e. ‘Consuelo’
  • ‘20’ : Uses the Mr20 volume-limited sample, i.e. ‘Esmeralda’
  • ‘21’ : Uses the Mr21 volume-limited sample, i.e. ‘Carmen’

catl_info : {‘members’, ‘groups’} str, optional

Option for which kind of catalogues to use.

Options:
  • members : Member galaxies of group catalogues
  • groups : Catalogues with group information.

halotype : {‘fof’, ‘so’} str, optional

Type of the dark matter halo of the simulation used to create the synthetic catalogues. This variable is set to fof by default.

Options:
  • ‘fof’: Friends-of-Friends halos.
  • ‘so’ : Spherical overdensity halos.

clf_method : {1, 2, 3} int, optional

Method for assigning galaxy properties to mock galaxies. This variable is set to 3 by default.

Options:
  • 1 : Independent assigment of (g-r) color, sersic, and log(ssfr)
  • 2 : (g-r) decides active/passive designation and draw values
    independently.
  • 3 : (g-r) decides active/passive designations, and
    assigns other galaxy properties for that given galaxy.

hod_n : {0, 1} int, optional

HOD model to use. Only relevant when catl_kind == mocks.

clf_seed : int, optional

Seed used for the CLF random seed. This variable is set to 1235 by default.

dv : float, optional

Difference between galaxy and mass velocity profiles (v_g-v_c)/(v_m-v_c). This value is set to 1.0 by default.

sigma_clf_c : float, optional

Value of the scatter in log(L) for central galaxies in the CLF. This variable is set to 0.1417 by default.

perf_opt : bool, optional

If True, it chooses to analyze the perfect set of synthetic catalogues. This variable is set to False by default.

print_filedir : bool, optional

If True, the output directory is printed onto the screen.
Returns:

catls_path : str

Path to the desired set of synthetic catalogues.
Raises:

LSSUtils_Error : Exception from LSSUtils_Error

Program exception if input parameters are accepted.
