A photometric and proper motion survey has been obtained in 2 directions at
intermediate latitude: (l=167.5ā, b=47.4ā;
Ī±2000ā=9h41m26s,Ī“2000ā=+49ā53ā²27ā²ā²) and
(l=278ā, b=47ā; Ī±2000ā=11h42m56s,
Ī“2000ā=ā12ā31ā²42ā²ā²). The survey covers 7.13 and 20.84 square
degrees, respectively. The limiting magnitude is about 18.5 in V for both
directions. We have derived the density laws for stars (MVāā„ 3.5) as a
function of distance from the galactic plane. The density laws for stars follow
a sum of two exponentials with scale heights of 240 pc (thin disk) and 790 pc
(thick disk), respectively. The local density of thick disk is found to be
6.1Ā±3 % relative to the thin disk. The kinematical distribution of stars
has been probed to distances up to 3.5 kpc above the galactic plane. New
estimates of the parameters of velocity ellipsoid have been derived for the
thick disk of the Galaxy. A comparison of our data sets with the Besan\c con
model star count predictions has been performed, giving a good agreement in the
magnitude range V = 13 to 18.Comment: 13 pages, 8 PS figures, To appear in A&
