v0.5.6

0.5.6 - 04/10/2022

Added

• added --dis-pid switch to import subcommand
• added --no-optimize switch to import subcommand

Changed

• improved documentation
• changed --silence-fastnlo to --silence-libraries, which now silences also APPLgrid
• improved import converter, which now is able to convert most APPLgrids and fastNLO tables on ploughshare

Fixed

• fixed corner cases of the REMAPPING string that were handled incorrectly
• made most tests of pineappl integration tests, which resolves that problem that cargo build had to be called before
• fixed problem in Grid::convolute_eko that lead to wrong result when subgrids had different x-grids

v0.5.5

0.5.5 - 25/08/2022

Added

• added support for choosing a specific member instead of the averaging over all PDFs for the central results for the pdfunc, plot and pull subcommands. For instance, pineappl pdfunc ... NNPDF40_nnlo_as_01180 calculates the central value using the average over all replicas, whereas pineappl pdfunc ... NNPDF40_nnlo_as_01180/0 uses the zeroth member. The calculated uncertainties are the same for both
• added support for converting APPLgrids in import
• added support plotting asymmetries with pineappl plot
• added new function to the C API, pineappl_grid_clone, which clones a given grid

Changed

• renamed the switch --silence-fastnlo to --silence-libraries, which also covers APPLgrid. For backwards compatibility the previous name still works

v0.5.4

0.5.4 - 08/07/2022

Added

• added new switch --force-positive to CLI to cut out negative PDF values
• exposed scale variation parameters to the Python API
• added the C functions pineappl_grid_key_value to read out metadata and pineappl_string_delete to delete string allocated from the previous function

v0.5.3

0.5.3 - 22/06/2022

Added

• added new switch --ignore-bin-limits to diff that ignores possibly different bin limits. However, the number of total bins must still be the same between both grids
• added support for FK tables in the subcommand import
• added new switches --digits-abs, --digits-rel and --digits to various subcommand to influence the number of (fractional) digits printed
• PDF relabeling support has been added. This means that all subcommands understand PDF specifications of the type pdfset=label, where pdfset must be an LHAPDF identifier, and results using this set are displayed using label instead of pdfset.
• added bin-dependent rescaling method. To use it through the CLI use pineappl ops --scale-by-bin=

Changed

• slightly changed the output of the CLI; indices of orders, bins and luminosities are now consistently abbreviated by o, b and l
• changed the output of the CLI to also print the units of the numbers

v0.5.3-beta.2

Release v0.5.3-beta.2

v0.5.3-beta.1

v0.5.3-beta.1

v0.5.3-beta

v0.5.3-beta

v0.5.2

0.5.2 - 29/03/2022

Added

• added new subcommand import, which at this stage converts fastNLO tables to PineAPPL grids. This program was previously an example and written in C++ and now has been removed.

v0.5.1

0.5.1 - 01/03/2022

Added

• added the --bins option to the CLI subcommand sum, which allows to sum bins together
• added the --fk-table option to the CLI subcommand optimize, which allows the optmization of FK tables based on assumptions of heavy-flavor PDFs
• added new subcommand ops which collects various modifying operations on grids. The switches --cc1 and --cc2 charge conjugate the first and second PDF, respectively, and charge conjugates the luminosity function correspondingly such that the convolutions are unchanged

Changed

• when running pineappl convolute ... -s 1 the scale-variation columns are no longer shown. The output would be zero, but this doesn’t make sense. All other values of -s are unaffected.
• added a further optimization to Grid::optimize that strips empty orders

Fixed

• fixed pineappl obl --bins, which had the wrong column headers if there were more than one observable

v0.5.0

0.5.0 - 11/02/2022

Added

• added support for DIS processes, which feature only a single hadron in the initial state
• added new C API function pineappl_grid_set_remapper
• added new subcommand sum to sum over bins of a grid
• added new subcommand pull to view where the differences between two PDF sets are coming from
• added an example program using the C API to convert fastNLO tables (of type fastNLOCoeffAddFix). Tables of type fastNLOCoeffAddFlex are not supported yet
• added a new switch --subgrid-pull to the plot subcommand; this generates several plots showing the where the pull between two PDFs comes from in x1 and x2, and also in rapidity y and invariant mass M
• improved the optimize method such that it removes all entries of a luminosity function that are empty across orders and bins. This required a change in merge, which now allows the merge of grids with different luminosities and orders
• enabled relabeling PDF sets, which means that they can now specified as LHAPDF-set-name=label, which uses the set LHAPDF-set-name to load it from LHAPDF, but label is the name that appears in the plot legend
• added new options to the subgrids command: --muf, --mur, --x1 and --x2 to print the corresponding grid values and --stats to print information about the space requirements of the subgrid type
• added new subcommand --delete, which allows to delete bins from a grid
• added new subcommand obl, which stands for orders (o), bins (b) and lumis (l), that shows information about the all contained subgrids in a grid; pineappl obl -l will replace pineappl lumis in the future
• added options --orders1, --orders2, --scale1 and --scale2 to the subcommand pineappl diff, which allow the selection of orders and scaling of grids that should be compared

Changed

• The command-line interface pineappl no longer prints both the differential and integrated cross sections. Instead it either prints the differential cross sections, or, if the switch -i or --integrated is given, the integrated cross sections (without bin limits and/or normalizations) are printed
• the C API functions pineappl_subgrid_q2_slice, pineappl_subgrid_filled_q2_slices and pineappl_subgrid_replace_and_delete have been replaced by pineappl_grid_export_q2_slice, pineappl_grid_nonzero_q2_slices and pineappl_grid_replace_and_delete, respectively.
• the C API function pineappl_subgrid_fill_q2_slice has been replaced by function pineappl_subgrid_import_q2_slice
• the C API function pineappl_subgrid_new has been replaced by a function with the similar name but different arguments
• changed the output of the pineappl subcommand channels, convolute and pdf_uncertainty. By default only the differential cross sections are shown (integrated numbers divided by bin widths), but the flag -i or --integrated can be given to switch to the integrated numbers, which are not divided by bin widths.
• slightly improved file sizes by introducing a type for empty subgrids: EmptySubgridV1
• vastly improved the output of the plot subcommand: bounding boxes are properly calculated now, added support for higher-dimensional distributions
• changed the plot subcommand such that the legend is put in between panels, thereby producing less overlapping elements
• replaced the C API functions pineappl_subgrid_new and pineappl_subgrid_import_q2_slice with pineappl_subgrid_new2 and pineappl_subgrid_import_mu2_slice, respectively. The latter support independent renormalization and factorization scales
• changed the names of pineappl_grid_export_q2_slice and pineappl_grid_nonzero_q2_slices to pineappl_grid_export_mu2_slice and pineappl_grid_nonzero_mu2_slices, respectively
• replaced C API-based Python interface with PyO3-based one
• the subcommand subgrids now does not print empty grids; the old behavior can be restored with the new switch --show-empty
• pineappl diff now behaves differently whenever luminities are different and errors out when this is the case. This can be adjusted using --ignore-lumis
