We have been doing a photometric and astrometric sample survey programme on
Schmidt plates in a few selected directions in the Galaxy with an aim to study
galactic stellar populations. In order to calibrate Schmidt plates
photometrically, it is necessary to have a number of photometric standards
which cover the entire range of magnitudes to be studied on the plates. As
Schmidt plates cover a wide area of the sky, the standards should also be
spread over the surface of the plate so as to minimise geometrical effects
present on the plate. This paper is first in a series of papers aimed at to
provide photometric standards in the selected galactic directions to be
studied. In this paper we present photometric magnitudes obtained through CCD
observation in the galactic direction (l=170deg, b=45deg) centered at
alpha(2000) = 9h 41m 20s and delta(2000) = +49deg 54' 20'' and covering an area
of 14 sq degs. B and V magnitudes have been obtained for a total of 214 stars
out of which for 73 stars U magnitudes also have been obtained. The magnitude
range covered is 11<V<21 and 0.18<B-V<1.85.Comment: Postscript file, 13 pages, 1 figure (figure available on request),
