Eventdisplay is a reconstruction and analysis pipeline for data of the VERITAS Imaging Atmospheric Cherenkov Telescopes (IACT). v492.0-rc1 is the first release candidate for v492. Do not use for science analysis Changelog Bugfixes Fix segmentation fault when exiting on error due to an empty tree in anasum. (#286) Limit number of errors printed when reading faulty VBF files to avoid TB large log files. (#298) New Feature Introduction of average zenith angle calculation per run in VTMVAEvaluator (fAverageZenithPerRun, calculate_average_zenith_angle()). (#281) Introduced new functionality for reconstructing events using any three telescopes out of four (primarily for Monte Carlo data and effective area calculations). Added new class: VMeanScaledVariables for mean scaled variable calculations. Updated VDispAnalyzer and VSimpleStereoReconstructor to support new reconstruction modes and calculation methods. Updated VInstrumentResponseFunctionRunParameter and related code to include new parameters for 3-telescope reconstruction. (#289) Add new command line parameter --minpedestalevents to set the minimum number of required pedestal events (default: 50). (#298) Maintenance Update SOFA to version 2023-10-11. (#284) Changes in tree structure and variable types to reduce size of output trees (mostly due to change of doubles to floats; removal of unused variables); reduction is on storage requirements is ~25%. (#288) Replaced many ROOT auto-generated header/source files (e.g., CData.h, CEffArea.h, CRunSummary.h, Cshowerpars.h, Ctpars.h, Ctelconfig.h) with hand-edited or cleaner C++ code, improving maintainability and readability. Moved implementation code from .C files to .cpp files, and deleted the old .C files. Adjusted several functions and constructors to reflect changes in how data and reconstruction methods are handled (e.g., CData and related classes now use cleaner, more explicit constructors). Functions that previously accepted "version" or "short" flags via integers now use explicit booleans for clarity. Removed the CEffFit class and related files. Pruned unused variables and methods, including some internal variables in VTMVAEvaluator, VTableLookupDataHandler, and others. Removed outdated warnings, TODO comments, and deprecated features. (#289) Introduce towncrier for changelogs. (#300) Fix github action worklows to compile Eventdisplay. Add cpp11 workflow.
