"A SCUBA Scanmap of the HDF: Measuring the bright end of the sub-mm source counts." Monthly Notices of the Royal Astronomical Society 330(3): 63-L670035-8711http://dx.doi.org/10.1046/j.1365-8711.2002.05347.xhttp://hdl.handle.net/10222/45478Using the 850 micron SCUBA camera on the JCMT and a scanning technique different from other sub-mm surveys, we have obtained a 125 square arcminute map centered on the Hubble Deep Field. The one-sigma sensitivity to point sources is roughly 3 mJy and thus our map probes the brighter end of the sub-mm source counts. We find 6 sources with a flux greater than about 12 mJy (>4 sigma) and, after a careful accounting of incompleteness and flux bias, estimate the integrated density of bright sources N(>12 mJy)= 164 (+77/-58) per square degree (68 per cent confidence bounds).article330363
