Abstract:
The results of CCD photometry in the seven-color Vilnius system are
given for 727 stars down to V∼17 mag in a 1.5 square degree field in
the region of dark cloud TGU H994 P1 (or LDN 1399, LDN 1400 and LDN
1402) in Camelopardalis. Using the intrinsic color indices and
photometric reddening-free Q-parameters, two-dimensional spectral
types for 73% of stars are determined.
Description:
Seven-color CCD photometry in the area shown in Figure 1 was obtained
in October of 2010 with the Maksutov-type 35/51cm telescope of the
Moletai Observa- tory in Lithuania and a VersArray 1300B liquid
nitrogen cooled camera. The camera has a backside-illuminated
1340x1300 pixel chip with pixel sizes 20x20um, with Unichrom
UV-enhancement coating. More information about the camera, including
its sensitivity function, is given by Zdanavicius & Zdanavicius
(2003BaltA..12..642Z 2003BaltA..12..642Z).

Note (2): The stars with two asterisks in the last column were not classified
in two dimensions since their images are asymmetrical, i.e., these stars are
double or multiple. The components of some of them are seen separately, but
they are closer than 7".
