args_init()

ast(ra1, dec1, ra2, dec2, radius, nneigh)

Matches two catalogues within a certain angular separation

ast_self(ra1, dec1, radius, type)

Matches the same catalogues within a certain angular separation

offsets_all(cat_file, comp_survey, settings)

survey_flux_scale.args_init()[source]
survey_flux_scale.ast(ra1, dec1, ra2, dec2, radius, nneigh)[source]

Matches two catalogues within a certain angular separation - Uses input of ra/dec in degrees and radius in arcsec - Output match has best matches for catalogue 1 and may have sources that

are matched to the same source in catalogue 2

  • Returns matched (within radius) skycoord array and distances

survey_flux_scale.ast_self(ra1, dec1, radius, type)[source]

Matches the same catalogues within a certain angular separation - Uses input of ra/dec in degrees and radius in arcsec - if type==gt then only keep those sources with matches father away, - if lt then chooses nearby matches
