Photometric observations obtained with the University of British Columbia (Thunderbird) Southern Observatory 0.5-m + CCD telescope are differential aperture magnitudes (Kron-Cousins B, V, R, I filters) and measured from stars in the Gaia Catalogue. The photometric observations are contained in an attached table (see below - OTmags_260923.txt).
The differential photometry was performed using A Basic Image Reduction Library (ABIRL) (A. C. Boley, 2021, A Basic Image Reduction Library). A second method involves creating a model galaxy, using the IRAF artdata packages, scaling it to the images and subtracting the host galaxy. The differential photometry was then performed using ABIRL (A. C. Boley, 2021, A Basic Image Reduction Library).
Note: Photometric redshifts of presumed host galaxies are marked 'p' and spectroscopic redshifts are marked 's'. All host redshifts are via the SDSS Skyserver.
