Description:
   This catalogue is a subset of the "CATALOGUE OF STELLAR GROUPS" (CSG, 
   Jaschek M. and Egret D., 1981). It provides a list of identifications,
   positions, UBV photometry, subgroup and references for chemically peculiar 
   stars corresponding to the following groups:
      TABLE 1: Helium abnormal stars
      TABLE 2: Ap stars
      TABLE 3: Am stars
   A bibliography file is also included.

Note on n_RAs:
   *     = RA was originally given to 0.1 minute. To homogenize the data 
             format, RA values were converted to seconds at ADC. RA values 
             in these records are only accurate to 6 seconds; therefore, 
             the decimal place is omitted.
   blank = RA was originally given to 0.1 second or is omitted.

Note on q_*:
   A = best
   D = worst
   : = uncertain

Note on Sub:
   The "helium abnormal stars" are B-type stars having either strong He lines
     (subgroup a) or weak He lines (subgroup c). Not included in this list are
     He-strong stars of Pop. II (extreme helium stars of Hunger), subdwarfs and
     objects like Ups Sgr. Stars being known as spectroscopic or photometric
     (or both) variables are flagged with a "v". 

   The "Ap stars" are B or A type stars with abnormally intensified lines of 
     different elements. Because of the sometimes conflicting subgroup assign-
     ments, only four subgroups have been retained.
     1 = Si and Si L4200 stars
     2 = Hg, Mn and Hg-Mn stars
     3 = Si combined with Cr, Eu, Sr, etc. (i.e. SiCr, SiEu, SiSr or SiCrEu)
     4 = Cr, Eu, Sr and combinations (i.e. CrEu, Cr, CrEuSr, etc.)

   The "Am stars" are A or early F type stars, in which the Balmer lines, the
     CaII lines and the metallic lines do not correspond to a unique spectral 
     type. No spectral classification of these stars is provided here. The
     reader is referred to Curchod and Hauck (1979) for detailed classifi-
     cations, when available.
