asso = ['ASSOC1', 'ASSOC2', 'ASSOC_TEV', 'ASSOC_GAM1', 'ASSOC_GAM2', 'ASSOC_GAM3']

energy_range = <Quantity [   100., 100000.] MeV>

Energy range used for the catalog.

Paper says that analysis uses data up to 300 GeV, but results are all quoted up to 100 GeV only to be consistent with previous catalogs.

flux_points

Flux points as a FluxPoints object.

flux_points_meta = {'n_sigma': 1, 'n_sigma_ul': 2, 'sed_type_init': 'flux', 'sqrt_ts_threshold_ul': 1}

flux_points_table

Flux points as a Table.

is_pointlike

name

Source name as a string.

position

Source position as an SkyCoord object.

row_index

Row index of source in catalog as an integer.
