Notes. Column (1): LABOCA source. Column (2): short name of LABOCA source. Columns (3, 4): J2000.0 coordinates of associated LABOCA counterparts either from VLA or Hα observations. Column (5): separation between nominal LABOCA bolometer and counterpart position. Column (6): spectrosopic (three digits after the decimal), photometric redshift (two digits after the decimal) and Hα imaging (one digit after the decimal) of the LABOCA counterpart. . Columns (7–14): flux measurements with Spitzer, Herschel, LABOCA and VLA. For multiple component counterparts as DKB01, DKB08 and DKB12, we give for the individual components the Spitzer and Herschel fluxes associated to the LABOCA detection. For the Herschel bands we give source detection errors. In case of the VLA measurements, we list the peak flux. Column (15): type of LABOCA counterpart. Secure counterparts are in bold face.
previously, Croft et al. (2005) obtained a rest-frame UV-spectroscopic redshift of z = 2.149 for the counterpart of DKB16
