The ESO Large Program 'Dissecting GAs Stripping Phenomena in galaxies' (http://web.oapd.inaf.it/gasp/, PI: B.Poggianti) is now releasing deep MUSE 3D cubes observed in wide field mode and natural seeing plus ancillary products from all the observations taken during the first three semesters of the program (P96, P97 and P98).

The scientific goal of the large programme is to study galaxies at z = 0.04-0.07 in different environments. The first half of the final sample (57/114) is now released. For each target galaxy, the released data products are the reduced and combined MUSE 3D data cubes that can be queried and downloaded using the Phase 3 query form. The 3D data cubes come together with an associated extracted 1D spectrum and associated maps of the emission-line fluxes for the Halpha and Hbeta emission, the Halpha 2D line-of-sight velocity field, the average star formation rate in four age bins, as well as luminosity-weighted stellar age and stellar mass density maps.

The released data come with a detailed description of the Large Program and a comprehensive data documentation here.
