Abstract:
We discuss identifications for 18 sources from our Max-Planck-
Millimeter-Bolometer (MAMBO) 1.2mm survey of the region surrounding
the NTT Deep Field. We have obtained accurate positions from Very
Large Array 1.4GHz interferometry, and in a few cases IRAM millimeter
interferometry, and have also made deep BVRIzJK imaging at ESO.
Description:
The NTT Deep Field was observed at 1.4GHz with the VLA in 2001 April
and May for 15hr in the B configuration (10 km maximum baseline).
Standard wide-field imaging mode was employed (50MHz total bandwidth,
with two polarizations and 16 spectral channels). We use the BVRIK
imaging of a field centered on the NDF that is described in Paper I,
Dannerbauer et al. (2002ApJ...573..473D 2002ApJ...573..473D).

--------------------------------------------------------------------------------
Note (1): The source MM J120534-0738.3 appears to be extended and may be
multiple or smeared. For consistency with the other sources, we list
its peak flux, which is effectively a lower limit to the true flux.
The source was included because of a reliable detection in total flux
and a 1.4GHz counterpart.
Note (2): To declare the quality of a radio source good, two criteria
have to be fulfilled: (1) Source does not disappear in the
"background-subtracted" radio map, and (2) no eye-catching
clustering of greater than 40µJy peaks in the adjacent region.

--------------------------------------------------------------------------------
Note (1): The optical/near-infrared objects is designated with a combination
of the short MAMBO number (Table 1) and a letter increasing with
distance from the interferometric position.
[DLL2004] MAMBO NTT-MM NNa in Simbad
Note (2): (a) 03d is not detected in B, z, and K, but retained because
of credible R and I detections
Note (3): For the measurements in the individual bands, we indicate cases
in which we consider the SExtractor aperture magnitudes more
uncertain, since the object is only tentatively (~) or not (!)
picked up by eye in the visual inspection.
Note (4): All magnitudes are on the Vega system except for the z magnitudes,
which are on the BD system (see text).
Note (5): Notes as follows:
b = Magnitude contaminated by 10a1.
d = Magnitude contaminated by nearby foreground galaxy.
e = Magnitude contaminated by nearby foreground star.
