J/PASP/106/967  Photometric Standard Stars       (Joergensen 1994)

Secondary Photometric Standard Stars for the Thuan-Gunn and Johnson-Kron-Cousins Systems. Joergensen Inger <Publ. Astron. Soc. Pac., 106, 967 (1994)> =1994PASP..106..967J
ADC_Keywords: Photometry, standards ; Photometry, special systems ; Photometry, UBV Abstract: CCD photometry is presented for 119 stars observed in the Thuan-Gunn photometric system (the passbands vgr). The sample includes 82 stars for which magnitudes in this system have not previously been published. Photometry in the Johnson-Kron-Cousins photometric system (BV or UBV) has been obtained for a sub-sample of 85 of the stars. Of those stars which are not primary standard stars for the Thuan-Gunn system 70 observed in Gunn r, 48 observed in Gunn g, and 37 observed in Gunn v have sufficient repeat measurements that they may be used as secondary standard stars for CCD photometry. The typical uncertain- ties for the magnitudes of these stars are 0.006 mag. File Summary:
