This collection contains imaging data products for the observing programme CAFFEINE whose data were acquired with the ArTéMiS camera at the APEX telescope from 2018 to 2022. The 48 imaged fields cover a total area of more than ~ 2.5 deg2, focused on the dense (AV > 10) parts of molecular clouds within about 3 kpc from the Sun. The released products include, per each field the 350 μm and 450 μm intensity maps with resolutions of 8'' and 10'' (half-power beam width), their related weight maps and multi-resolution H2 column density maps. These datasets have been carefully calibrated and combined with Herschel/SPIRE data to recover large-scale emission that cannot be detected from the ground with ArTéMiS. The column density maps have been derived by including additional Herschel data at 160 μm and 250 μm and have a resolution ranging from ~8'' in their denser inner parts (AV > 40) to 18.2'' in the lower-density outer parts (AV < 40). For more details, refer to the accompanying release documentation or the publication by Mattern et al.
