Changelog#

This page shows the release notes for every released version of the package.

The first entry corresponds always to a future release and gives a glimpse of what can be found in the development version.

Please, check the project Milestones for a detailed roadmap of the next planned releases.

v0.5.0 (April, 2022)#

This release will brings huge improvements to the performance of the pipeline and the software package.

Some of the changes are related to the improvements in the interface to the DIRAC grid. Please, consult that for more details about its latest release.

The performance of the pipeline has been validated successfully on a Prod5b simulation for the Alpha configuration at the North site under specific observational settings. Tests on a similar configuration for the South site are ongoing. From now on, performance results will be showcased at this website.

The benchmarking has become a package module (protopipe.benchmarking) and a new protopipe-BENCHMARK script has been added to the suite of available commands.

The pipeline makes now use of ctapipe v0.11.0 and pyirf v0.5.0. For more details, please consult the merged Pull Requests listed below.

Please, remember that protopipe and its interface are open-source projects and anyone can contribute to it. It is possible to perform full-scale analyses and contribute to the production of CTA performances for different science cases or perform studies that require big amounts of data.

0.4.0 (Feb 22th, 2021)#

Summary#

This release brings many improvements of which the most relevant are summarised here depending on their scope within the pipeline workflow.

Performance-wise, protopipe caught up with the EventDisplay and CTAMARS historical pipelines starting from about 500 GeV onwards. Below this threshold, even if compatible with requirements, the sensitivity diverges. The cause seems to be a low-energy effect delimited to the steps before model training.

  • All pipeline

    • upgrade to the API of ctapipe 0.9.1

    • documentation also on readthedocs and link to Zenodo

    • Continuous Integration is now performed on GitHub

    • New benchmarks have been added

    • Reference analysis and benchmarks results have been updated

  • Data training

    • calibration benchmarks need only ctapipe-stage1-process

    • write_dl1 has become data_training

    • DL1 parameters and (optionally) images are merged in a single file

    • DL1 parameters names as in ctapipe and they are in degrees (TelescopeFrame)

    • scale correction with the effective focal length

    • fixed bugs and wrong behaviors

  • Modeling and DL2 production

    • fixed bugs and wrong behaviors

    • Added missing features to get closer to CTAMARS

  • DL3

    • the performance step is now based on the pyirf library

    • performance results are stored here

0.2.0 (Oct 24th, 2019)#

Summary#

  • Released Oct 24, 2019

  • 3 contributor(s)

  • 7 pull requests

Description

protopipe 0.2 now fully supports the stable release of ctapipe 0.7.0.

The main improvements involve the calibration process (high gain selected by default), the direction reconstruction and new camera-type labels.

Code based on pywi/pywi-cta libraries, relevant for wavelet-based image cleaning, has been removed in favor of ctapipe or made completely optional where needed. Wavelet cleaning is still optional but will need those two libraries to be additionally installed. Tailcut-based cleaning is now faster.

The README has been improved with installation, basic use, and developer instructions. Dependencies are listed in protopipe_environment.yaml and have been simplified.

The auxiliary scripts merge_tables.py and merge.sh have been added to allow merging of DL1 and DL2 HDF5 tables.

The mars_cleaning_1st_pass method is now imported from _ctapipe_. Novel code using the largest cluster of survived pixels (number_of_islands and largest_island methods in the event_preparer module) has been hardcoded in _protopipe_ and will disappear with the next release of _ctapipe_.

Model estimators now load the camera types directly from the analysis .yaml configuration file.

Summary#

  • Released Oct 1, 2019

  • X contributor(s)

  • X pull request(s)

Description

The write_dl1 and write_dl2 tools can now save an additional file through the flag --save-images when applied to a single run. This file will contain the original and calibrated (after gain selection) photoelectron images per event. A new method save_fig has been introduced in the utils module, so that model_diagnostic can save images also in PNG format. Additional docstrings and PEP8 formatting have been added throughout the code.
