Abstract:
    Using the  data observed with  the Photoelectric Astrolabe  Mark II of
    the Beijing Astronomical Observatory (PPA) during the period from 1982
    to  1990, the Fourth Preliminary Catalogue  of Stars (PACP4) have been
    Compiled. It  consists of 1969 stars including  650 FK5 stars and 1319
    GC stars.  The  mean  precisions  of  position  corrections  in  right
    ascension and  declination are  4.1 ms  and 0.067",  respectively. The
    declinations  are from +11 deg to +69 deg. The magnitudes are from 0.1
    to 7.3. The mean epoch of observations is 1986.8.
