====== Atacama Pathfinder Experiment (APEX)/ArTéMiS instrument====== We present the CAFFEINE survey (PI: P. André) that was carried out between 2018 and 2022 as a large program of the European Southern Observatory (ESO). . The data were taken with the ArTéMiS bolometer-array camera at the Atacama Pathfinder EXperiment (APEX) telescope in Chile. \\ This survey observed the densest portions of all southern molecular clouds at d ≲ 3 kpc, at wavelenghts of 350 and 450 μm, and with an angular resolution of 8" and 10" respectively. Units of the maps are MJy/sr. Healpix maps made by D. Paradis. === Reference === * 'Understanding the star formation efficiency in dense gas: Initial results from the CAFFEINE survey with ArTéMiS' by Matter et al., 2024, A&A, 688, 163 https://ui.adsabs.harvard.edu/abs/2024A%2526A...688A.163M
