Eventdisplay v490 is a major update of the reconstruction and analysis code used for VERITAS.
This update includes significant changes which break the analysis of older versions at certain stages.

Running this version requires also updates to the newest versions of Eventdisplay_AnalysisScripts_VTS and Eventdisplay_AnalysisFiles_VTS (private repository).

This is a pre-release with substantial changes expected in near future. Please try it out, but don't use it for science publications.
Changes with relation to v490-alpha.1 are:

dispBDT angular resolution

  • add correct addition of VPM pointing monitor correction to dispBDT direction reconstruction

Writing of image/border pixel lists on evndisp stage

Option -writeimagepixellist to evndisp allows to write out list of pixel (with integrated charge and timing) surviving the image cleaning.

This option increases the output files of evndisp by approximately a factor 2.5-3. It is therefore switched off by default.

Written are image, border pixels, and one additional ring of pixels around them.

Written the pars trees:

PixelListN : PixelListN/i
PixelID   : PixelID[PixelListN]/i 
PixelType : PixelType[PixelListN]/i 
PixelIntensity : PixelIntensity[PixelListN]/F
PixelTimingT0 : PixelTimingT0[PixelListN]/F

PixelType indicates the following:

  • PixelType == 1: image pixel
  • PixelType == 2: border pixel
  • PixelType == 3: neighbour pixel to image/border

Use DB text files instead of direct query to VERITAS data base

New functionality to read DB text files. This allows faster parallel processing of many runs without opening up too many connections to the VERITAS database. Requires reading of DB information using the scripts available in the db_scripts directory of Eventdisplay_AnalysisScripts_VTS. Possibly also a step to remove the ROOT-mysql dependency and allow for easier compilation.
