Abstract

Using the 850-μm SCUBA camera on the JCMT and a scanning technique different from other sub-mm surveys, we have obtained a 125 arcmin2 map centred on the Hubble Deep Field. The 1σ sensitivity to point sources is roughly 3 mJy and thus our map probes the brighter end of the sub-mm source counts. We find six sources with a flux greater than about 12 mJy (>4σ) and, after a careful accounting of incompleteness and flux bias, estimate the integrated density of bright sources (68 per cent confidence bounds).
