discov_num notes refcode
BU 469 POU4167. ALADIN shows nothing at the expected coordinates of POU4179.
Pouteau's astrometry and photometry for POU4167 and POU4179 are very Pou1933
similar and epoch-1900 coordinates differ only in one digit
(195519.0+2427.1 versus 195559.0+2427.1) - conclude they are the same
pair and coordinate difference is due to a typographical error.
