Abstract

Calibrated data for 143 flat-spectrum extragalactic radio sources are presented at a wavelength of 850 microns covering a five-year period from April 2000. The data, obtained at the James Clerk Maxwell Telescope using the SCUBA camera in pointing mode, were analysed using an automated pipeline process based on the Observatory Reduction and Acquisition Control - Data Reduction (ORAC-DR) system. This paper describes the techniques used to analyse and calibrate the data, and presents the database of results along with a representative sample of the better-sampled lightcurves. A re-analysis of previously published data from 1997 to 2000 is also presented. The combined catalogue, comprising 10493 flux density measurements, provides a unique and valuable resource for studies of extragalactic radio sources.
