Description:
In studying this region Purgathofer (1964AnWie..26...37P 1964AnWie..26...37P) [the SIMBAD
numbering], Hoag et al.(1961PUSNO..17..343H 1961PUSNO..17..343H), and Dombrovskii and
Hagen-Thorn (1964TrLen..20...75D 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 1964AnWie..26...37P), those of the form HoagNN and DHNN are from
Hoag et al. (1961PUSNO..17..343H 1961PUSNO..17..343H) and Dombrovskii and Hagen-Thorn
(1964TrLen..20...75D 1964TrLen..20...75D). Hoag et al. (1961PUSNO..17..343H 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 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.
