run_sql_query_contaminants

tessilator.contaminants.run_sql_query_contaminants(t_target, pix_radius=5.0, mag_lim=3.0, tot_attempts=3)[source]

Perform an SQL Query to identify neighbouring contaminants.

If an analysis of flux contribution from neighbouring contaminants is specified, this function generates the SQL query to identify targets within a specified pixel radius. The function returns a table of Gaia information on the neighbouring sources which is used to quantify the flux contamination within the target aperture.

Parameters:
t_targetastropy.table.Table

The input table

pix_radiusfloat, optional, default=5.0

The maximum angular distance (in arcsecs) to search for contaminants

Returns:
t_gaiaastropy.table.Table

The Gaia results table from the SQL query.
