J/A+AS/136/1 CPASJ2 catalogue (Manrique+ 1999) ================================================================================ Second San Juan photoelectric astrolabe catalogue Manrique W.T., Lu L., Perdomo R., Podesta R.C., Wang Z., Actis E.L., Zeng F., Zeng Z., Alonso E., Pacheco A.M., Bustos G. =1999A&AS..136....1M ================================================================================ ADC_Keywords: Positional data ; Magnitudes ; Spectral types Keywords: catalogue - astrometry - references systems Abstract: According to the cooperation between Beijing, San Juan and La Plata Astronomical Observatories, the photoelectric astrolabe Mark II(PAII) of the Beijing Astronomical Observatory was moved and installed at the San Juan Observatory, Argentina in January, 1992 for observations of the catalogue of stars in the southern hemisphere. The first observing period was from Feb. 23, 1992 to Mar. 31, 1997. Using the data observed in San Juan with the instrument during this period, residuals for 11002 stars are reduced from about 405700 observations of stars over 1532 days. The mean precision of the residuals is +/-0.043". The Second Catalogue of Stars (CPASJ2) has been compiled from double transits at both the eastern and western passages. There are 5241 stars in this catalogue, including 1225 FK5/FK4Supp stars, 794 FK5Ext stars, 1084 SRS stars, 937 CAMC4 stars, 310 GC stars and 891 IMF stars. The mean precisions are +/-3.2ms and +/-0.057" in right ascension and declination, respectively. The magnitudes of stars are from 2.0 to 11.5. The declinations are from -3{deg} to -60{deg}. The mean epoch is 1994.9. Finally, systematic corrections of(CPASJ2-FK5) are given.
