Note:1976ApJS...32..217S:
Two formats (NNN and HHMM+DDd) are cross-identified. Notice that a few objects are giant HII regions in galaxies . (ex. Tol 89 in NGC 5398). Tol 26 = CTIO 1230-275 is a PN (1992, Acker+ catalog).
1978ApJ...221..776B:
Use exclusively a format with 1950 eq. coordinates, as proposed in col. 2 of Table 1. NN numbering = BFW78
1979ApJ...231..653B:
Use exclusively a format with 1950 eq. coordinates, as proposed in col. 2 of Table 2. NN numbering = BW79
