Abstract:
We present the redshift distribution of the Submillimetre Common-User
Bolometer Array (SCUBA) Half Degree Survey (SHADES) galaxy population
based on the rest-frame radio-mm-far-infrared (FIR) colours of 120
robustly detected 850um sources in the Lockman Hole East (LH) and
Subaru XMM-Newton Deep Field (SXDF). The redshift distribution derived
from the full spectral energy distribution (SED) information is shown
to be narrower than that determined from the radiosub-mm spectral
index, as more photometric bands contribute to a higher redshift
accuracy.

Note (1): Notes on which radio counterpart (from Ivison et al. 2007, Cat.
J/MNRAS/380/199) is used in the computation of photo-z, in case of
ambiguity (N for Northern component, S for Southern component, etc.,
or co-added if the flux densities from all components are summed).
Note (2): a = This source has a robust 1.4GHz association in the data set
of Ivison et al. (2002MNRAS.337....1I 2002MNRAS.337....1I), but it is below the robustness
level adopted for the analysis in this paper, and thus we will make
use of the revised 1.4GHz photometry of Ivison et al. (2007, Cat.
J/MNRAS/380/199) as an upper limit.
Note (3): Flag for sources for which the redshifts have reported
ambiguities in their radio/optical counterpart associations,
or where the redshifts are otherwise under scrutiny.
