Abstract: Debris discs - analogous to the Asteroid and Kuiper-Edgeworth belts in theSolar system - have so far mostly been identified and studied in thermalemission shortward of 100 um. The Herschel space observatory and the SCUBA-2camera on the James Clerk Maxwell Telescope will allow efficient photometricsurveying at 70 to 850 um, which allow for the detection of cooler discs notyet discovered, and the measurement of disc masses and temperatures whencombined with shorter wavelength photometry. The SCUBA-2 Unbiased Nearby StarsSUNS survey and the DEBRIS Herschel Open Time Key Project are complimentarylegacy surveys observing samples of ~500 nearby stellar systems. To maximisethe legacy value of these surveys, great care has gone into the targetselection process. This paper describes the target selection process andpresents the target lists of these two surveys.
