Description:
Results of NIR (JHK) photometry for about 1000 stars in 10 fields
around IRAS sources previously recognized as related to star forming
sites in the Vela Molecular Ridge C and D clouds. Only objects at
least detected in the K band are listed. IRAS sources are indicated by
the short designation adopted in the Paper (# IRS). Due to the
presence of bad pixels or because of the closeness to the image edge,
photometry could not be performed on a few objects and in such cases
magnitudes and errors are not given at all. Note that, for IRS 33,
coordinates are offsets (in arcsec) from source # 4.

Note (1): If unspecified, the magnitude is an upper limit
Note (2): Notes:
PH: problems in H
AB: possible saturation in J, H and K bands
PF: by PSF fitting
NE: diffuse nebular emission
Note (3): Unfortunately, we could not perform astrometry on field IRS33
since there are too few NIR sources with visible counterparts whose
positions are listed in the GSC. Hence, we were forced to assign
offsets from a reference objects.
The position of the centre of the IRAS uncertainty ellipse, which,
although probably near it, does not correspond to that of source 4:
08:59:25.8-43:26:07 (J2000).
