The full format of these cubes is described in the Weilbacher et al. paper.
Subcubes
If one does not need a full cube but only a small spatial part of it, one can use the CutOut tool provided by the MUSE collaboration to extract (small) subcubes of the full dataset.
Brief usage instructions: In both cases, select the cube from the list to load it and dismiss the dialog. Then you can move around with the mouse (click the arrow button), choose wavelength range and spatial extraction size on the right, and then select regions to cut out (with the scissors button). After the tool has created the subcube, you can use the download link on the right (the floppy disk).
Note: The subcubes extracted here only contain data (DATA) and variance (STAT) cubes, but no images.
Maps
All maps presented in the paper are reproduced here. We also provide FITS versions of all of them.
Color images
Color composite using fluxes of three emission lines, with blue: Hbeta, green: [N II] 6584, and red: [S II] 6731.Link to FITS files:
Color composite using fluxes of three emission lines, with blue: Hbeta, green: [N II] 6584, and red: [S II] 6731. Dereddened using the Balmer decrement.Link to FITS files:
Enhanced color image, using the three ionization levels of oxygen detectable with the MUSE data: red: [O III] 5007, green: [O II] 7320, blue: [O I] 6300, all corrected for extinction using the Balmer decrement.Link to FITS files:
Extinction map of the central Orion Nebula, as derived from the Hα to Hβ flux ratio, displayed as c_Hβ. Bright stars are marked again with black circles, the smoothed contours are 0.4 ≤ c_Hβ ≤ 1.2 in steps of 0.2.
Electron temperature (T_e) of M42 computed from [S III]Link to FITS files: unsmoothed, smoothed (with 5×5 pixel median filter)
Electron temperature (T_e) computed from [N II]Link to FITS files: unsmoothed, smoothed (with 5×5 pixel median filter)
Electron density
Electron density (N_e) of M42 computed from [Cl III]Link to FITS files: unsmoothed, smoothed (with 5×5 pixel median filter)
Electron density (N_e) of M42 computed from [S II]Link to FITS files: unsmoothed, smoothed (with 3×3 pixel median filter)
Spatial velocity field
Velocity field as traced by the lines Hα (with respect to barycentric velocity). The locations of the brighter stars in the field are marked as black circles, further noticeable features are annotated or marked in green or gray.
Velocity field as traced by [N ii] 6584 relative to Hα. Note that the linear color scale is asymmetric. The locations of the brighter stars in the field are marked as black circles.Link to FITS files:
