Abstract
Abstract. A robust measurement of the clustering amplitude of the sub-mm population of starburst galaxies requires large-area surveys ( ≫ 1 deg 2). The largest-format arrays subtend only 10 arcmin 2 on the sky and hence scan-mapping is a necessary observing mode. Providing realistic representations of the extragalactic sky and atmosphere, as the input to a detailed simulator of the telescope and instrument performance, allows important decisions to made about the design of large-area fully-sampled surveys and observing strategies. In this paper we present preliminary simulations that include detector noise, time-constants and array geometry, telescope pointing errors, scan speeds and scanning angles, sky noise and sky rotation. GENERATING REALISTIC SYNTHETIC TIME-SERIES A mapping simulator has been developed to generate synthetic bolometer time-series data and associated astrometric information which are then run through a realistic reduction pipeline
