The UGC was used to confirm that the coordinate is correct for VV 29 and erroneous for VV 10. The UGC position for VV 10 = UGC 10814 was adopted. 11 The VV position is substantially different (>400") from positions for the object in other catalogs. The VV position has been assumed to be in error because two or more other catalogs agree on a different position. The UGC position has been adopted. 12 Same as for 11, but the OSU position has been adopted. 13 The position in the VV Atlas, and the position listed for the VV object in the OSU are in disagreement. The true position has been established to be close to that of the OSU by the use of overlay transparencies on the POSS. The OSU position has been adopted. 14 Same as for 13, but the OSU position is not very good either, so a new position has been measured (accurate to about 1'). ================================================================================
