Extreme sources not ending up in image catalogue

[tikk3r]

I have a field with a 3C source in it well within the pointing

yet it does not appear in image_catalogue.csv. This messes up dd-calibration severely due to their nature (and also the definition of image_catalogue being >10 mJy sources). It is present in extreme_catalogue.csv, however. Perhaps it is removed explicitly somewhere.

Found the culprit:

    lotss_catalogue = my_lotss_catalogue(
        RATar,
        DECTar,
        Radius=lotss_radius,
        bright_limit_Jy=bright_limit_Jy,
        faint_limit_Jy=0.0,
        outfile=lotss_catalogue,
        use_vo=True,
    )

so it is indeed explicitly removed. With the default settings it will exclude sources brighter than 5 Jy from ending up in the image_catalogue.csv based on the downloaded LoTSS catalogue.

Another issue is that the lower limit for the extreme catalogue is 10 Jy, so sources in the 5-10 Jy range are ignored completely and don't end up in either catalogue.
