ADC_Keywords: Photometry, UBV 

Description:
   UBV photometry is presented for stars from AGK3R, NPZT, the Yale Bright Star
   Catalog (HR), and the FK5 faint extension. Stars with previously published
   UBV data were not selected. Observations were taken at the Kvistaberg
   Observatory and La Palma.

Introduction:
   Mean errors are given in the latest paper as follows: 
   for HR stars, 0.015 mag in V, 0.008 mag in B-V, 0.011 mag in U-B (U < 10), 
   0.027 mag in U-B (U > 10); for non-HR stars, 0.013 mag in V, 0.009 mag in 
   B-V, 0.011 mag in U-B (U < 10), 0.031 mag in U-B (U > 10).
