v0.6.3

0.6.3 - 12/12/2023

Added

• added Grid::dedup_channels, the C function pineappl_grid_dedup_channels and the new switch --dedup-channels to the CLI that detect equal subgrids and reduce the space requirements of a grid
• added a new panel double_ratio_pdf to the pineappl plot tool
• added a Python binding for the Grid::merge method

Removed

• removed the functions of pineappl_grid_export_mu2_slice, pineappl_grid_nonzero_mu2_slices, pineappl_subgrid_delete, pineappl_grid_replace_and_delete, pineappl_subgrid_import_mu2_slice and pineappl_subgrid_new2, which were only used in the C++ programs that were the predecessors of the export and import functionality now implemented in the CLI

Fixed

• fixed a bug that caused channels with PID=0 gluons to not evolve when the metadata key-value pair lumi_id_types=pdg_mc_ids was not present. Now when this metadata is not present it is assumed PDG MC IDs are used
