VizieR Online Data Catalog: HerMES Large Mode Survey catalogue (Asboth+, 2016)

The HerMES Large Mode Survey (HeLMS) consists of a large area shallow observation of an equatorial field at wavelengths of 250, 350 and 500um, obtained using the SPIRE aboard the Herschel Space Observatory. HeLMS is an extension of HerMES (Oliver et al., 2012MNRAS.424.1614O, Cat. VIII/95 and VIII/103), a 'wedding cake' type survey containing small and deep maps and larger shallower observations of different fields. HeLMS covers about 302deg² of the sky, making it the largest area observed in the HerMES.

The HeLMS field spans 23h14m<RA<1h16m and -9°<DE<+9°, an equatorial region with low cirrus contamination. It was designed to have a large overlap with the Sloan Digital Sky Survey;s Stripe 82 field (Abazajian et al., 2009ApJS..182..543A), one of the most highly observed areas of the sky, with extensive multiwavelength ancillary data coverage. The equatorial area has the advantage that it can be observed from almost any ground-based telescope site in the world.
