v0.6.0

This is an interim release, after some major refactoring, and before we add the automatic gain selection and refactored container classes. It's not intended yet for production.

Some Major changes since last release:

• new EventSource class hierarchy for reading event data, which now supports simulation and testbench data from multiple camera prototypes (notably CHEC, SST-1M, NectarCam)
• new EventSeeker class for (inefficient) random event access.
• a much improved Factory class
• re-organized event data structure (still evolving) - all scripts not in ctapipe must be changed to work with the new data items that were re-named (a migration guide will be given in the 0.7 release)
• better HDF5 table output, supporting merging multiple Containers into a single output table
• improvements to Muon analysis, and the muon example script
• improvements to the calibration classes
• big improvements to the Instrument classes
• lots of cleanups and bug fixes
• much more...

v0.5.2

release version 0.5.2

instrument restructuring

• instrument module now has much more rich functionality (SubarrayDescription, TelescopeDescription, OpticsDescription classes added
• no more need to construct CameraGeometry and others manually, they are created in the hessio_event_source
• all new code should use event.inst.subarray
• the old inst.tel_pos, inst.optics_foclen, etc, will be phased out in the next point release (but still exist in this release)

ready for sensitivity plots

Lots of improvements and bug fixes, some highlights listed below.

Major framework changes:

• removed astropy_helpers and ctapipe_extras sub-repos (the latter is now a seprate module)
• improved setup, versioning, and package system
• improved documentation
• working unit tests
• support for travisCI documentation builds
• simplified instrument module
• faster and more unified CameraGeometry, with support for cameras in FITS files
• basic provenance system to record input/output/parameter metadata
• improved coordinate systems
• event-wise HDF5 table io
• improved camera and array displays
• ctapipe-dump-instrument tool

Major algorithm changes:

• complete Muon analysis
• complete Hillas reconstruction (HillasReconstructor)
• energy estimation with machine learning
• ImPACT reconstruction and fast table interpolation
• cleaned up ChargeExtractors and WaveFormCleaners
• simplified calibration (and added CameraCalibrator helper)

v0.4.0

API Changes

• New Container structure that follows CTA data levels better

• Created dl0.py to handle to data volume reduction in the conversion from r1 to dl0. Created reductors.py to contain the date volume reductors that can be passed as an argument to CameraDL0Reducer in dl0.py.
• Corrected r1.py to loop through all telescopes that have data in the event
• Removed dl0 correction for mc files - this is now handled by r1.py
• Removed mc.py and mycam.py as they do not fit in the new calib methodology
• Created r1 calibrator component - should replace mc.py
