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’]

from_astro_catalog(p_cat_radec: common.sky.catalog.CatalogAstroSourcesBasic, p_limit_elevation=0)

add sources from an astro catalog and convert coordinate in elevation, direction

p_cat : catalaog in ra , dec coordinate

p_limit_elevation deg

Note

need set_ptg_instru

Parameters:

• p_cat_radec (CatalogAstroSourcesBasic) – catalog in ra, dec coordinates
• p_limit_elevation (float) – limit in elevation in deg. Default is 0.

from_astro_catalog_with_spectrum(p_cat_radec)

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

get_row_with_name(name)

intensity_with_channel(nb_chan)

raz all catalog and change format

plot_on_astro_sphere(p_title=None, show=True, save=None)

plot the sources on the sky, with RA and DEC

Note

different to plot_on_sphere that plot with elev and dir

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.

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_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)

write the catalog table into a fits file

If the file already exists, it is overwrite.

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

set_ptg_instru(p_ptg_instru: common.mission.attitude.AttitudeVT)

set the pointing object associated to this catalog

Parameters:p_ptg_instru (pointing_instrument.AttitudeVT) – pointing of the instrument for this catalog

to_astro_catalog()

return an astro catalog in ra, dec coordinates based on the source table

Note

need set_ptg_instru

Returns:astro catalog Return type:CatalogAstroSourcesBasic
