UGC 568: diameter applied based on a measurement on 2MASS and a distance of 1,758 Mpc which is way out of the redshift values, a calculated mean distance by NED. The large distance may be due to a measurement by the SDSS Supernova Survey (see here) where a distance was at 2,540 Mpc (8.2 billion light years) using supernova SDSS-II SN 10649, which what makes it weird is that the redshift of the supernova is at 0.04571, equivalent to 183 Mpc.
I don't know how they got that, but it gives the galaxy an absurdly large diameter (~780 kpc) far larger than others in the list. A modest calculation using the provided scale (893 pc/arcsec on Virgo + Great Attractor + Shapley) and the major axis in KS 2MASS total of 91.40 arcsec gives just 81.6 kpc, about 266,000 light years. Putting this down here as a flagged galaxy. SkyFlubbler (talk) 02:13, 9 July 2022 (UTC)[reply]
