frb.surveys.heasarc

Surveys to be accessed through the HEASARC interface (via astroquery

class frb.surveys.heasarc.HEASARC_Survey(coord, radius, mission, **kwargs)

Bases: SurveyCoord

Class to handle queries on the HEASARC survey. Uses astroquery for searching the Heasarc SQL database.

Args:

• coord (SkyCoord) – Coordiante for surveying around

• radius (Angle) – Search radius around the coordinate

• mission (str) – Mission served by HEASAR for the data searches

__init__(coord, radius, mission, **kwargs)

get_catalog()

Grab a catalog of sources around the input coordinate to the search radius

Returns:

Catalog of sources returned

Return type:

astropy.table.Table
