cta-observatory/ctapipe: v0.7.0

What's Changed since v0.6.2

This is a major release with breaking API changes from the 0.6.x series. Scripts using ctapipe-0.6.x may need to be updated.

Notable API changes:

• removed Factory classes (factories now in constructor)
• EventSources are now constructed using EventSource.from_url() or EventSource.from_config(), thought the convenience function event_source() still works as before.
• The default EventSource for MC data is now the SimTelEventSource instead of HESSIOEventSource. This means libhessio is no longer required, as SimTelEventSource uses a pure-python implementation called pyeventio.
• Other EventSources are now plug-ins that are automatically detected if installed.
• the camera calibration code and ChargeExtractor have been totally re-factored and simplified. Note that it's lower-level API has thus changed.
• ctapipe-extra is not longer strictly required to be installed (though some functionality will not work if it is not installed like constructing a CameraGeometry from name if no CTAPIPE_SVC_PATH is set by the user).
• New EngineeringCameraFrame coordinate system that allows one to draw a camera as it would look when parked (rather than the standard SimTelArray coordinate system).
• naming scheme for telescopes has changed in the instrument module (it is now <optics type>_<optics_subtype>_<camera type>, e.g. LST_LST_LSTCam or SST_ASTRI_CHEC)

Improvements:

• ctapipe no longer needs any compilation (the c code in CameraCalibrator has been removed and replaced with Numba functionality for speed and maintainability improvements), which means the package can be made architecture-independent (though python must generate the *.pyc files on install, which takes a bit longer)
• HDF5TableWriter now can write tables to any group(s) in an HDF5 file, and can optionally append prefixes to the output columns of a Container (e.g. width → hillas_width)
• HillasReconstructor now supports non-parallel (e.g. divergent or convergent) pointings
• many speed improvements for calibration and neighbor matrix operations.
• New tailcuts (picture/boundary) function for multiple nearest-neighbor cleaning (MARS-like)
