v0.10.0.post1

v0.10.0.post1

Add v0.10.0 doi to README, test for automatic pypi deployment.

v0.10.0

What's Changed since v0.9.1

DL1 file support is much improved with DL1Writer and DL1EventSource components, which together allow one to write and read DL1 data trivially. Any code that used EventSource to read data will automatically be able to read DL1 data with no change needed. R0-DL0 data can be analyzed and written to DL1 using the Tool ctapipe-stage1 and merged together using ctapipe-merge

ctapipe-extra is no longer needed (but still supported). Test files are downloaded automatically from the data server.

The analysis and calibration has been improved, with time shift corrections now applied when available, and uncertainties on Hillas parameters.

The event_source helper function was removed and you don't need to use EventSource.from_url or EventSource.from_config anymore, using EventSource('/path/to/file') will "just work" and return the compatible event source if one is available.

v0.9.0

This release should be compatible with v0.8.0, but with some bug fixes, speed improvements.

Notable bug fix:

• the DL1 format generated by v0.8.0 was missing the telescope trigger time, due to a bug which was fixed in this version.

API changes:

• EventSeeker (which provides random access to event sources) now relies on the get_event_index() and get_event_id() methods to move between events, rather than an implicit __get__ function. Code that used it should change as follows:

  previously:

  event = seeker[12]  # move to event at index 12
  event = seeker["1233"] # move to event id 1233

  now:

  event = seeker.get_event_index(12)
  event = seeker.get_event_id(1233)

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:

• gain-channel selection is applied at the DL1 level, so event.dl1.tel[i].image is now 1D (whereas before it was 2D, with the first index as the gain channel)
• 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)
