Description |
We make available FITS images of: - The image cubes containing the hydrogen and helium 41alpha lines, prior to primary-beam correction: "FIELD_B3_spw1_12M_h41a.JvM.image.contsub.fits". - The regridded free-free estimation for each protocluster at the standard ALMA-IMF "cleanest" continuum frequencies of 98.5 and 224.5 GHz. The filenames start with the basename "FIELD_B3_spw1_12M_h41a.JvM.image.contsub", which is standard naming within the ALMA-IMF data reduction pipeline see (Ginsburg et al. 2022). Then are followed by ".m0.ffXXX.XGHz_Y.Ysigma.regr", which denotes the fact that they are obtained from a moment 0 map, the frequency of the calculation, the threshold in the moment 0 map, and the applied regridding. Finally, the filenames end with either ".pbcor.fits" or just with ".fits" depending on whether primary-beam correction is applied or not at the end of the procedure. - The error of the free-free estimation. Following the same nomenclature as above but with ".err" in the filename. - The "cleanest" continuum image from the release of Ginsburg et al. (2022), convolved to the beamsize of the H41alpha cube. The filename is the same as in the ALMA-IMF data release, but ending with .conv.fits. - An estimate of pure dust continuum emission, from the subtraction of the continuum maps minus the free-free estimation, with and without PB correction. The basename of these estimation images of pure-dust is the same as for the original continuum images, but ending with ".conv.ffsub_Y.Ysigma.fits. |
