class frb.surveys.nedlvs.NEDLVS(coord, radius=<Quantity 90. deg>, cosmo=None, **kwargs)[source]

Bases: SurveyCoord

A class to handle local NED Local Volume Sample queries. This requires the LVS table to be downloaded from https://ned.ipac.caltech.edu/NED::LVS/ and linked via the environment variable NEDLVS

get_column_names()[source]
get_catalog(z_lim=inf, impact_par_lim=<Quantity inf Mpc>, query_fields=None, print_query=False)[source]

Get the catalog of objects within the given limits of redshift, impact parameter, and angular separation.

Args:

  • z_lim (float) – The maximum redshift of the objects to include in the catalog.

  • impact_par_lim (Quantity) – The maximum impact parameter of the objects to include in the catalog.

  • ang_sep_lim (Quantity) – The maximum angular separation of the objects to include in the catalog.

  • query_fields (list) – The fields to include in the catalog. If None, the default fields are used.

Returns:

A table of objects within the given limits.
