NGC/IC Project Restoration Effort

===== NGC 2524 and NGC 2528 are two galaxies found by Stephan in 1877. His positions are referred to BD +39 2062 = SAO 060607, so should be accurate within his measurement error of 2-3 arcsec. NGC 2524 is indeed where Stephan places it, but NGC 2528 is not south following as it should be if his position is correct. However, north preceding NGC 2524, there is a galaxy that fits Stephan's description perfectly. Looking at his measurements and plotting the galaxies and the comparison star, I found what Stephan must have done. The difference in position between the two galaxies is exactly equal to the difference in position between the star and NGC 2528. This means that Stephan actually measured NGC 2528 with respect to NGC 2524, not with respect to the star. He apparently forgot to make a note to that effect, so when he reduced his observations later, he assumed that both observations were referred to the star. Re-reducing his data taking this error into account gives positions in very close agreement with those in the GSC (aside from an offset in declination of about 15 arcsec because Stephan's declination for the comparison star is off by that amount). Esmiol has pretty well sorted out the problems, but his table entries are a bit misleading. The galaxy is labeled "Anon" and "Anonyme" in the tables of offsets and final positions, but "2528" in the table of descriptions. My thanks to Steve Gottlieb for pointing this out. The PGC and RC3 have the correct identifications.

===== NGC 2524 17.5" (2/24/90): fairly faint, fairly small, bright core, almost stellar nucleus, oval NW-SE. Forms a pair with NGC 2528 = UGC 4227 10' WNW.
