The faint counterparts of MAMBO millimeter sources near the New Technology Telescope Deep Field. Dannerbauer H., Lehnert M.D., Lutz D., Tacconi L., Bertoldi F., Carilli C., Genzel R., Menten K.M. <Astrophys. J., 606, 664-682 (2004)> =2004ApJ...606..664D
ADC_Keywords: Radio sources ; Infrared sources ; Redshifts ; Photometry Keywords: galaxies: formation - galaxies: high-redshift - galaxies: starburst - infrared: galaxies - submillimeter 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). File Summary:

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.
