Data products from the joint reconstruction of Galactic HI and H2 (via CO). Primary data products: These are the posterior samples of the "densities" (HI and H2) in cm^-3 and "auxiliary" fields (i.e. the three components of the Galactic velocity field and the two spatially resolved line-widths) in km/s on our Sun-centered HEALPix-times-radius grid. These files also contain two tables with the centres and edges of the pixelisation in radial direction. The nearest (farthest) bin is at approximately 50 pc (28 kpc). The HEALPix dimension is ordered using the "nested" scheme. samples_densities_hpixr.fits samples_auxiliary_hpixr.fits Interpolated to a regular grid: For convenience, we also provide versions linearly interpolated to regular, Cartesian grids. Due to the strongly inhomogeneous original numerical grid, these interpolated versions contain regions of significant over/undersampling. To mitigate this a little, we provide a "local" (800 x 800 x 320 grid points with -1.25 kpc < x < 1.25 kpc, -1.25 kpc < y < 1.25 kpc and -0.5 kpc < z < 0.5 kpc) and a "global" (1250 x 1250 x 125 grid points with -12 kpc < x < 28 kpc, -20 kpc < y < 20 kpc, -2 kpc < z < 2 kpc) version. The origin (0,0,0) is defined by the position of the Sun and positive x points towards the Galactic centre. In an attempt to keep the file sizes reasonable, we provide the mean and standard deviation of each field instead of all eight individual samples. mean_std_densities_xyz_global.fits mean_std_densities_xyz_local.fits mean_std_auxiliary_xyz_global.fits mean_std_auxiliary_xyz_local.fits
