   NED object is AM 0421-404; Reference is 1987AMCAT.C...0000A

   Each photograph in Volume II is identified by seven numbers on the edge of
 the print (e.g. AM 1227-445). The first four figures are its right ascension
 in hours and minutes of time, and are followed by the negative declination in
 degrees, plus the minutes truncated after the first figure. By looking in
 Volume I at the positions, which are ordered by right ascension, any object
 illustrated can be further identified. There is a white bar, two arc minutes
 long, in the south-east corner of each photograph. The sense of the printing
 is as seen on the sky with north, west, south and east occuring in clock-wise
 order.
