Abstract:
Photoelectric data on the Johnson-Kron-Cousins UBVRI broadband
photometric system are provided for a set of stars that have been used
as spectrophotometric standard stars for the Hubble Space Telescope.
Description:
The Kitt Peak National Observatory (KPNO) 1.3m telescope was
scheduled for this program for 101 nights in the interval of 1985
September to 1991 June.
