Deep 3D data cubes obtained with the Multi-Unit Spectroscopic Explorer (MUSE) in the wide field mode have been released from early data acquired in June – August 2014, plus the initial two periods of MUSE operations, P94 and P95 (October 2014 through September 2015). These deep cubes are now published via the ESO Science Archive as reduced data.The MUSE-DEEP data collection contains 209 cubes.

Each deep datacube combines the input files obtained across multiple observing blocks (OBs) and, where appropriate, from multiple visits to the same target. The MUSE-DEEP combined cubes are complementary to the already existing OB-based MUSE datacubes (see previous announcement). Some of the deep datacubes are produced from slightly more than 120 input files, and the deepest datacubes represent a total integration time of 30 hrs. The number of deep cubes will grow with time, with future processing cadence being once per period or yearly. The data have been reduced with the MUSE pipeline, versions muse-1.6.1 and higher (see the pipelines page). The data format for the MUSE-DEEP cubes and their associated information follows the ESO Science Data Products standard for datacubes and is the same as for the single OB datacubes.

The MUSE-DEEP cubes tagged "MUSE-DEEP" can be queried and downloaded using the Phase 3 generic query form which provides access to all Phase 3 data, or the Phase 3 spectral data query form with query parameters suited to harvest 3D cube data. More details about the MUSE-DEEP data are available in the associated Phase 3 data release description.
