Abstract: This is the release of reduced IFU datacubes from the MUSE spectrograph, taken in the Wide Field Mode. MUSE, the Multi-Unit Spectroscopic Explorer, is an Integral Field Spectrograph located at the VLT UT4 telescope. The instru- ment samples almost the full optical wavelength range with a mean resolution of 3000. In the Wide- Field mode (WFM), it has a 1 squared arcmin field of view (FOV) sampling the sky with 0.2 arcsec- onds spatial pixels. In this mode, observations are carried out under natural seeing (WFM-NOAO) or, since 2017, also assisted by the UT4 AO system (WFM-AO). The Narrow-Field mode (NFM) has a FOV of 7.4”x7.4” and samples with 0.025 arcseconds spatial pixels. It is offered since P103 and is supported by laser tomography, as NFM-AO. This release is an open stream release. It is complete from the begin of operations, 2014-09-13, until present. Data from the Science Verification periods (NOAO in June and August 2014, AO in August and September 2017) are also included. The data content grows with time as new data are being acquired and processed (approximately with monthly cadence and with a delay of 1 or 2 months). The data have most of their instrument signature removed: they have been pre-processed, de-biased, flat- fielded, astrometrically calibrated, sky-subtracted, wavelength-calibrated, and fluxed. Their wave- length scale has been corrected to the barycentric reference system. In the last step they usually have been combined (except for documented cases) and resampled. The sky correction either uses user-defined SKY pointings, or – if not available - the sky is determined from the observations directly, applying a sky model. Errors are propagated throughout the reduction and provided in the final datacube.
Other: This is a dynamic dataset; it is growing as new data is added. The DOI refers to the newest available dataset.
