Overview

GammaLib 1.7 is a major release that adds significant functionality.

In particular, this release provides:

  • Support for INTEGRAL/SPI data analysis
  • Response caching for all instruments
  • A radial ring as new spatial model
  • A spectral table as new spectral model

Bug fixes

  • [3199] - Fix ambiguity problem in GSkyDir::posang() and GSkyDir::posang_deg().
  • [3179] - Fix GModelSpatialDiffuseCube pickeling issue.
  • [3126] - Avoid rounding errors in GSkyMap operators.
  • [3012] - Exclude upper edge boundary in GSkyMap::contains() method.
  • [2917] - Fix GTime.utc() precision bug.
  • Correctly write model attributes in GCOMModelDRBFitting class.

Improvements

  • Add equality and non-equality operators to GSkyRegionCircle class.
  • [3202] - Replace GCTAResponseCache class by GResponseCache class.
