Description:
Results of NIR (JHK) photometry for about 1300 stars in 12 fields
around IRAS sources previously identified as Class I sources towards
the Vela Molecular Ridge D-cloud. 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 as for IRS 13, coordinates are
offsets (in arcsec) from source # 29.

Note (1):
If unspecified, the magnitude is an upper limit
Note (2):
IN: integrated brightness of nebular emission
BN: possible blob of nebular emission
KS: possible saturation in K band
JH: possible saturation in J and H bands
AB: possible saturation in J, H and K bands
Note (3):
Unfortunately, we could not perform astrometry on field IRS13 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 29.
This is RA = 08:37:31.8 DE = -41:09:14 (1950).
