This new data release includes a flux map at 870 μm for the galaxy M83 (NGC 5236). It is obtained from the combination of the observations taken with the Large APEX Bolometer Camera (LABOCA) under the ESO programme id 081.C-0827(A), PI A. Lundgren, between 2008-06-19 and 2008-06-30.
The total exposure time of the flux map is 0.5 hours, it has a signal to noise ratio of 47 in the galaxy central region, while the inner spiral arms are detected with a signal to noise ratio of more than 3. The atmospheric window of 870 μm, in which LABOCA operates, provides the opportunity to study the dust in the interstellar medium and the grain size distribution.
