Preliminary data product release for the ArXiV version of the above mentioned paper. The final version is expected to be published at the CDS. If already available, please use it instead of this release. General Description This data collection contains the numerical results of the Gamma-ray sky reconstructions discussed in the first revision of the above-mentioned paper. The results of each reconstruction are stored in a separate ZIP archive. For each reconstruction and sky component, we provide the following data products: the reconstructed posterior samples of I^c_ij (see definition in paper) posterior sample means and sample standard deviations These are contained in HDF5 files named after the components, following the naming conventions in the paper. Each HDF5 file contains the data groups 'samples' and 'stats', with the former containing the posterior samples and the latter containing the posterior sample mean and standard deviation. Pixelation in the spatial domain The sky sphere is pixelated following the HEALPix 'RING' scheme with an Nside of 128. Pixelation in the spectral (energy) domain The energy dimension is pixelated as a regular grid on logarithmic energy scale. The energy bin boundaries are the same for both reconstructions and are stored in the file 'energy_bins.hdf5'. A note on summary statistics The posterior mean and standard deviations contained in the HDF5 files are calculated directly from the posterior samples as given. However, for many analyses it is more appropriate to use the mean and standard deviation on logarithmic scale.
