This and many early (first ~150) objects from (Weinberger+ 1999) have very poor and inaccurate positions which make it sometimes (very) difficult to identify the intended galaxy of this ZOAG catalog. I initially wrote up an extensive list of the exact offsets and correct positions of the first 75 galaxies but there was an error submitting the annotation and the text was lost in its entirety. In lieu of that, I will say that virtually all of the galaxies numbered 1-100 in the vizier ingestion of this catalog are actually northeast (+RA +DEC) of where their recorded J2000 position is, often around circa (+30, +30) arcseconds, and many around (+150 +170)-(+190 +220) arcseconds, such that individually matching a galaxy to the catalog is very difficult to do credibly, and the association only becomes clear when analyzing several consecutive galaxies and noticing the consistent offsets from the reported position. Several are separately cataloged in other catalogs as a result of the lack of identification.
The issue becomes less severe after the first hundred objects or so, but continues at a 20-30" level through the entirety of the ~3600 object catalog causing wrong identifications to still occasionally happen. A manual review of the coordinates all objects published by (Weinberger+ 1999) would be highly needed, because otherwise it serves little use for many of its cataloged galaxies.
