The IRAS Revised Bright Galaxy Sample (RBGS)

3.2. Revisions from the Original BGS₁ and BGS₂

Table 2 is a list of objects from the BGS₁ + BGS₂ that have been omitted from the RBGS because their revised 60 µm flux density is less than or equal to 5.24 Jy. The table caption explains why some of these objects were listed with S(60µm) leq 5.24 Jy in BGS₁.

^a These objects were listed in Table 1(b) of BGS₁ (Soifer et al. 1989) as having S(60µm) < 5.24 Jy. However, they were also included in the main BGS₁ catalog listing [Table 1(a)], because of their presence in an earlier compilation (Soifer et al. 1987). Since some readers may have been confused regarding the status of these objects, these sources are listed here again and omitted in Table 1 of this work to clarify their status.

Table 3 is a list of objects from the BGS₁ + BGS₂ which have revised cross-identifications in various catalogs. These corrected, revised cross-identifications were determined by visualizing the IRAS uncertainty ellipses superimposed on the DSS images (Figure 1), and by using current information available in NED.

Table 4 is a summary of the 39 objects which are new members of the RBGS. These objects were missed during compilation of the BGS₁ + BGS₂ for a variety of reasons. Their presence in the RBGS is the result of comprehensive searches utilizing NED in conjunction with queries of the IRAS catalogs, followed by examination of the IRAS scan data using SCANPI.

^a SCANPI S(60µm) profile zero-crossing size is comparable to optical size of the galaxy, and SCANPI S(12µm) and S(25µm) values are larger than or comparable to those of Rice et al. (1988) and Rice (1993), so SCANPI zero-crossing values are adopted in RBGS for this object.
