ADC_Keywords: Photometry, UBV; Stars, bright
Description:
The data presented in this catalogue are the results of multicolor
photometric observations of stars listed in the Bright Star Catalog.
Observations were made on the 21-in, 28-in and 60-in telescopes of the
Lunar and Planetary Laboratory, and at Tonanzintla Observatory on the
40-in telescope of the Observatorio Astronomico Nacional, Universidad
Nacional de Mexico. This catalog of UBV photometry on almost 5000
bright stars covers the entire sky by including southern Cape
photometry transformed to the UBV system.
