Matt reviewed his recent announcement of a new version of AmpTools, now at version 0.5. Although the package is under development all the time, recently the user interface has been streamlined and should be simpler to use. However, user code must change to be compatible with this new version. Matt has changed the relevant code in the repository, so to use it one must have the new AmpTools version.
The functionality is nearly the same as before, a few new features have been added.
Matt reports that he is now collaborating more closely with the group at INFN Genoa and they have submitted various feature requests, in particular to do fits in terms of moments. Some recent work has also been in collaboration with Adam Szczepaniak.
Reconstruction sub-group reports
PID RF Beam Bunch Selection
Paul reported on his scheme for finding multiple RF beam buckets in multi-track events. Reconstructed tracks vote on their preference for the event bucket based on their times at the BCAL or TOF. See his wiki page for details.
Mark asked that at some future meeting Paul present some quantitative measures of the performance of the algorithm.
Future of reconstruction sub-group reports
We decided that although very useful in the past, we will drop the reports as standing agenda items. Progress in these areas will continue to be reported, but on an as-needed basis.
This raised the issue of our current offline task list. Now that the bulk of reconstruction factories have been written, the major issues don't fit our task list as well as they used to. Mark will propose a list of offline projects that we will track in the future. We can then discuss both composition of the list and its scope.
Dmitry pointed out that there are systems to facilitate software project management on a high-level, above that supported by the Mantis system we are using. We thought that to start out, we would use some ad-hoc system. We can get more formal later if we have to.
