The LABOCA Extended Deep Field South Submillimetre Survey (LESS or the LABOCA ECDFS Submm Survey) is a 350 hour 870 um Survey of the Extended Chandra Deep Field-South Survey field (0.5 x 0.5 degrees) using the Atacama Pathfinder Experiment (APEX) telescope's LABOCA submillimetre camera. It was performed in 2007 and 2008.
A subsequent survey, ALESS (or ALMA-LESS), looks at the same field using ALMA.
