Title: Faint UBVRI Photometric Standard Star fields: CTIO
Abstract:
Telescope time is being requested for continued enhancement and
development of broad-band (UBVRI) CCD photometric standard stars. Use
of such standard stars permits the combination and inter-comparison of
the brightness and color measurements of celestial phenomena made by
different investigators with different sets of equipment, on land or in
space. The continued efforts at improving the broad-band UBVRI
photometric system is important so that all astronomers using and
needing photometric results can be confident of the zero points,
transformations, and systematics of their results. This work also will
allow the intercomparison of UBVRI and SDSS photometry in common fields.
The stars and fields upon which observational work will continue are
distributed around the celestial equator, as well as in a zone centered
at -50 degrees declination. Standard star publications by the author
are some of the most heavily referenced articles in astronomy. There is
no doubt but that the photometric sequences being established via this
observing proposal also will see extensive use.
