Changelog

This page contains a summary of changes between the official cwepr releases. Only the biggest changes are listed here. A complete and detailed log of all changes is available through the GitHub Repository Browser.

Version 0.4.0

Released 2023-07-15

Note: Starting with this version, cwepr requires ASpecD >= 0.8.0.

New features

  • Add Frequency Correction with offset: This keeps the hyperfine splitting values.

  • Amplitude sweep importer for Magnettech. Averaging of temperature and Q-Values of the single measurements. A warning is issued if the values vary too much.

  • Implement Digital Filter into metadata.

  • Data is imported according to its file extension specified in the recipe.

  • Added support for cwepr-infofile version 0.1.5

  • Handling of data from Magnettech-Files: The filtered first derivative spectrum is taken by its name by default. The parameter can be set to also import other data curves such as the second derivative or the sinus part.

Changes

  • Extend cw-EPR primer: additional notes on recording spectra

Fixes

  • Fix bug in analysis.FitOnData by using a helper dataset.

  • Fix some metadata in magnettech importer (experiment.runs -> signal_channel.accumulations, correctly import spectrometer metadata, bring time stamp to same timezone.)

  • Do range extraction and interpolation (instead of interpolation only) in GoniometerSweepImporter.

  • Fix FieldCorrection to update correct axis and update metadata.

  • Win-EPR importer makes less mistakes in guessing the unit of the field axis.

Version 0.3.0

Released 2022-07-24

New features

  • Add linear fit with fixed intercept to FitOnData, renamed function accordingly.

  • Importer for NIEHS dat, lmb, and exp files

Version 0.2.1

Released 2022-06-12

New features

  • Reference to publication in documentation and colophon of reports.

Fixes

  • Import units correctly using the BES3T importer.

  • Magnettech goniometer sweep importer handles situation without info file.

  • Fix for import and gathering of metadata of both sources in WinEPR Importer.

  • Units are imported correctly from par file in WinEPR importer.

Version 0.2.0

Released 2021-11-28

Note: Starting with this version, cwepr requires Python >=3.7

New features

  • Importer for Bruker EMX/ESP file format (.par/.spc)

  • g value can be provided for cwepr.analysis.FieldCalibration

  • New module utils for general-purpose functions regarding cw-EPR spectroscopy

  • Functions cwepr.utils.convert_g2mT() and cwepr.utils.convert_mT2g() to convert between magnetic field values (in mT) and g values

  • Plotters can add g axis as second axis opposite the magnetic field axis.

  • cwepr.plotting.PowerSweepAnalysisPlotter for graphical representation of power saturation curves including a second axis with the actual microwave power.

  • List of example recipes, available both in the source repository and from the documentation.
