Description
Eventdisplay is a reconstruction and analysis pipeline for data of the VERITAS Imaging Atmospheric Cherenkov Telescopes (IACT).
v491-rc2 is the second release candidate for v491. It is possible to use this for tests and careful science analysis
v491-rc2 includes a bug fix in TMVAEvaluator.
Version v491 is a major release with significant changes in the reconstruction algorithm and important bug fixes.
Improvements
- significant improved high-energy reconstruction by
- allow to fill lookup tables with loss factors larger than those used in the
evndispstage. - allow to re-analyse events with loss factors larger than those used in the
evndispstage. - improved dispBDT reconstruction with much better hyper parameter (derived from optimization on CTAO simulations)
- added dispBDT energy reconstruction to allow to reconstruct events with large loss factors
- improved BDT gamma/hadron separation; addition of DispAbsSumWeigth variable for gamma/hadron separation
- allow to fill lookup tables with loss factors larger than those used in the
- 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.
