Functions

synthesizer.load_data.load_camels.load_CAMELS_Astrid(_dir='.', snap_name='snap_090.hdf5', group_name='fof_subhalo_tab_090.hdf5', group_dir=None, dtm=0.3, physical=True, age_lookup=True, age_lookup_delta_a=0.0001, **kwargs)[source]

Load CAMELS-Astrid galaxies

Parameters:

  • dir (string) – data location

  • snap_name (string) – snapshot filename

  • group_name (string) – subfind / FOF filename

  • group_dir (string) – optional argument specifying lcoation of fof file if different to snapshot

  • dtm (float) – dust to metals ratio for all gas particles

  • physical (bool) – Should properties be converted to physical?

  • age_lookup (bool) – Create a lookup table for ages

  • age_lookup_delta_a (float) – Scale factor resolution of the age lookup

Returns:

ParticleGalaxy object containing star and gas particle

Return type:

galaxies (object)
