Methods Documentation

add_from_catalog(other_catalog)¶

add to this catalog the sources from the other catalog

if metadata from the catalogs do not match, an error is raised

Parameters:	other_catalog (CatalogBase) – catalog from sources are added

add_src(info_src)¶

add a source to the catalog

‘elev’,’dir’,’intensity’,’name’

Parameters:	info_src ([ float, float, float, string ]) – [‘elev’,’dir’,’intensity’,’name’]

get_catalog()¶

return the table of the catalog

Retunr:	table of the catalog
Return type:	astropy.table.Table

get_nb_element()¶

return the number of sources in the catalog

The number of sources is computed from the ‘name’ column

Returns:	number of sources in the catalog
Return type:	int

plot_on_sphere(p_title=None, show=True, save=None)¶

plot the sources on a sphere

Warning

self.name_file_cat must be manually set

Parameters:	p_title (string) – title of the plot. Default=None show (bool) – show the plot. Default=True. save (string) – PATH/name of the file to save in. If None, no saving. Default=None.

read_cat_swift_light()[source]¶

set the source table with sources from the swift-BAT catalog

swift-BAT catalog is in common/data/cat/BAT_70m_catalog_20nov2012.fits

name is set from ‘counterpart’

flux if ‘flux’ convert to keV/20

read_catalog(name_file)¶

init the sources table from a fits file

If there already are sources in the catalog, there are deleted.

The file must be a fits file with a table data

Parameters:	name_file (string) – PATH/name of the file to read

remove_src(p_name)¶

remove a source from the catalog

Parameters:	p_name (string) – name of source to remove

save_catalog(name_file)¶
