What's Changed since v0.14.0

The main change in this release is that the SimTelEventSource will use the effective focal length, which is the focal length corrected for the mean effect of aberrations like coma, by default. This will raise an error if this information is not available in the input file (which is the case for files from before prod5).

To analyze these files with ctapipe 0.15, you need to pass the SimTelEventSource.focal_length_choice="nominal". Using the effective focal length much improves the off-axis angular resolution of e.g. the HillasReconstructor.

  • Use effective focal length by default, always guess telescope names from nominal (#1910) @maxnoe
  • Fix ctapipe license in tutorial (#1907) @maxnoe
  • Fix merge tool in case --skip-images is given but no images in input file (#1906) @maxnoe
  • Keep z coordinate in tilted ground frame (#1903) @maxnoe
  • Fix HDF5EventSource.len to take max_events into account (#1897) @maxnoe
  • Add alias for prov log (#1890) @maxnoe
  • update README for v0.14.0 (#1886) @kosack
  • Fix setting up logging hierarchy, fixes #1882 (#1883) @maxnoe
