Herschel-ATLAS: counterparts from the ultraviolet-near-infrared in the science demonstration phase catalogue

Abstract:

We present a technique to identify optical counterparts of 250-μm-selected sources from theHerschel-ATLAS survey. Of the 6621 250μm > 32-mJy sources in our science demonstration catalogue we find that ~60 per cent have counterparts brighter thanr= 22.4mag in the Sloan Digital Sky Survey. Applying a likelihood ratio technique we are able to identify 2423 of the counterparts with a reliabilityR> 0.8. This is approximately 37 per cent of the full 250-μm catalogue. We have estimated photome...
