The Herschel ULIRG Survey (HERUS) was the largest extragalactic Open Time survey (OT1_dfarrah_1, 250 hrs) carried out by the Herschel Space Observatory. HERUS is a flux limited sample of low-redshift ULIRGs comprising the 43 ULIRGs from the IRAS PSC-z survey (Saunders et al. 2000) with 60 micron fluxes greater than 1.8 Jy.
