Description:
Johnson CCD photometry was performed in the two subgroups of the
association Cepheus OB3, for selected fields each containing at least
one star with previous UBV photoelectric photometry. Photometry for
about 1000 stars down to visual magnitude 21 is provided, although the
completeness tests show that the sample is complete down to V=19mag.
Individual errors were assigned to the magnitude and colours for each
star. Colour-colour and colour-magnitude diagrams are shown.
Astrometric positions of the stars are also given. Description of the
reduction procedure is fully detailed.

b: The positions for the stars in this field were calculated taking
as origin BHJ15br (PPM24029, BD+61 2361, SAO20299, HD216629,
HIC113017).
Its frame coordinates are x=289.059 y=479.793, and the J2000
equatorial coordinates taken from PPM catalogue alpha=22h53m15.63s,
delta=+62deg 08' 44.76". It was not obtained V magnitude for BHJ15br
and, thus, we can not give photometry for this star.
c: The only positional information found for stars in this field comes
from the cross-identification BHJ65 = BD+62 2158 (alpha(B1950)=23h
00.1m, delta(B1950)=+62deg33'). The resulting absolute positions
accuracy is, so, not better than 1'.
