Title: Faint UBVRI Photometric Standard Star fields: KPNO
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 KPNO observing will take advantage of the availability of a
larger telescope, the 2.1-m, than is available at CTIO. The stars and
fields upon which observational work will continue are distributed
around the celestial equator, as well as in a zone centered at +45
degrees declination.
Standard star publications by the author are some of the most
heavily referenced in astronomy. There is no doubt but that the
photometric sequences being established via this observing proposal also
will see extensive use.
