Abstract:
Using the infrared photometry data extracted from the 2MASS, IRAS
and MSX databases, 50 suspected young stellar objects (YSOs) are
selected from about 37500 infrared objects in the 3x3deg2 area
with the center at (l,b=142.5,+1.0), in the vicinity of the young
stellar object GL 490 in the dark cloud T 942 (Dobashi et al.,
2005PASJ...57S...1D 2005PASJ...57S...1D, Cat. VII/244). The spectral energy
distributions between 700nm and 100um suggest that most of
the selected objects may be YSOs of classes I and II. In the
color-magnitude diagram Ks vs. H-Ks the suspected YSOs occupy an area
right of the main sequence what can be interpreted as being caused by
the effects of luminosity, interstellar and circumstellar reddening
and infrared thermal emission in circumstellar envelopes and disks.

Note (1): Note for individual stars as follows:
SL 149 = binary, in K brighter component at 6"
SL 162 = binary, in K fainter component at 6"
SL 164 = no object in R and very faint in K. Wrong coordinates?
SL 165 = in R with tail, in K no tail
SL 167 = nearby YSOs separated by 19"
SL 168 = nearby YSOs separated by 19"
SL 174 = very faint in R and K. Wrong coordinates and IRAS identification?
SL 175 = probably heavily reddened Herbig Ae/Be star (in the J-H vs.
H-Ks diagram they lie well below the intrinsic T Tauri line)
SL 176 = probably heavily reddened Herbig Ae/Be star (in the J-H vs.
