Abstract:
On the photon counter data observed with Photoeleetric Transit
Instrument of Beijing Astronomical Observatory during the period from
1988 to 1990, corrections of right ascensions of 324 stars are given.
The mean precision (<m{DELTA}αcosδ>) is 4.7ms. The mean
observational epoch is 1989.7. The relations of residuals with
magnitudes and spectral types are discussed and given respectively.
Finally the systematic corrections (PPCP4-FK4) are also analysed.
