Corwin's Notes
=====
NGC 1257 is a double star. Bigourdan saw this object on two nights, but only
estimated its position once. Since the BD position of his comparison star is
also an estimate (and is actually closer to a slightly fainter star about 1.7
arcmin east-southeast), the NGC position is off. Consequently, the number
N1257 has been mistakenly assigned to CGCG 540-073 in RNGC, PGC, and RC3.
Bigourdan's estimated position, however, falls within an arcminute of the
double, and he notes the two neighboring stars in his description. The
identity is secure.
