Eventdisplay - release v491.0

Eventdisplay is a reconstruction and analysis pipeline for data of the VERITAS Imaging Atmospheric Cherenkov Telescopes (IACT).

Version v491 is a major release with significant changes in the reconstruction algorithm and important bug fixes.

Detailed release note and tests can be found in the dedicated v491 release repository, see here.

Main Improvements

• significant improved high-energy reconstruction by
  • allow to fill lookup tables with loss factors larger than those used in the evndisp stage.
  • allow to re-analyse events with loss factors larger than those used in the evndisp stage.
  • improved dispBDT reconstruction with much better hyper parameter settings (derived from optimization on CTAO simulations)
  • added dispBDT energy reconstruction to allow to reconstruct events with large loss factors (migrated from CTAO analysis)
  • improved BDT gamma/hadron separation; addition of DispAbsSumWeigth variable for gamma/hadron separation
• telescope-dependent pedestal variations are now taken correctly into account in lookup table code
  • before: tables where accessed using the average pedvars
  • this change requires many and deep changes in both lookup table writing and reading codes.
