From 39ade326b56cd6deb6778a0edb8de464e21132ab Mon Sep 17 00:00:00 2001 From: Carlo Fuselli Date: Thu, 7 Dec 2023 10:26:11 +0100 Subject: [PATCH] Peaks and events (#285) >> Peak processing Restructured plugins Fixed area fraction top calculation Peak classification works well, moved to peak_basics (to tune with options) Introduced gain correction (to tune with options, for now) Introduced position reconstruction with center of gravity >> Events processing Restructured plugins Added simple S2 area correction for electron lifetime (to tune with options, for now) Added positions at event level Added new peak info at event level: waveform and area per channel >> Extra A new function to see default options per plugin (st.get_config_defaults) More plugins registered in the context (and tested!) --------- Co-authored-by: acolijn Co-authored-by: tobiasdenhollander --- .readthedocs.yaml | 3 +- amstrax/common.py | 29 +++++ amstrax/contexts.py | 21 ++-- amstrax/plugins/events/__init__.py | 17 ++- amstrax/plugins/events/corrected_areas.py | 90 +++++--------- amstrax/plugins/events/energy_estimates.py | 36 ------ .../plugins/events/event_area_per_channel.py | 100 +++++++++++++++ amstrax/plugins/events/event_basics.py | 15 +-- amstrax/plugins/events/event_info.py | 4 +- amstrax/plugins/events/event_positions.py | 100 +++------------ amstrax/plugins/events/event_waveform.py | 69 +++++++++++ amstrax/plugins/events/events.py | 13 +- amstrax/plugins/peaks/__init__.py | 6 -
