Description:
    In studying this region Purgathofer (1964AnWie..26...37P) [the SIMBAD
    numbering], Hoag et al.(1961PUSNO..17..343H), and Dombrovskii and
    Hagen-Thorn (1964TrLen..20...75D) each set up their own numbering
    system; subsequent authors used one or another of those or variants or
    combinations.
    The region covered is 2 degrees in diameter, centered at:
    (2000) RA 04 04 53.28 dec +62 19 20.7.
    This is about 15' west of the cluster, the position of HD 25290.

Note (1): Designations of the form NGC 1502 NN are from Purgathofer
     (1964AnWie..26...37P), those of the form HoagNN and DHNN are from
     Hoag et al. (1961PUSNO..17..343H) and Dombrovskii and Hagen-Thorn
     (1964TrLen..20...75D). Hoag et al. (1961PUSNO..17..343H) give a table
     of 26 numbered stars with photoelectric photometry, and a second,
     longer, unnumbered table of stars with photographic photometry, 
     which includes the stars in the other table.  Reiman and Pfau
     (1987AN....308..111R) numbered the stars in the second table by
     continuing the numbering from the first table, calling the first
     star in the second table 27; this system is used here.
Note (2): 4067-862 and 4067-873: The 1855 coordinates for BD +61 649 lies
     almost exactly halfway between these two GSC stars. Additionally,
     4067-414 10.8mag, is about 2.6' from the position 4068-347: This is
     evidently DH97, though DH do not give a BD number. There are no other
     stars of similar brightness in the vicinity in the GSC or on the
     Palomar Sky Survey.

Note (1): NGC 1502 1 and 2: There is some confusion in the literature over
     identification of these two similar stars. In SIMBAD the lower HD
     number HD25638 = 1 is east of HD25639 = 2, and all the other
     identifications given there are consistent with this. PPM and DH are
     two of the places with the reverse of SIMBAD.
Note (2): These Hoag et al. stars are not in the GSC:
     24, 45, 58, 59, 63, 67, 69, 71, 80, 83, 85, 87, 88, 89, 92, 93, 94.
