v0.3.0

State of the software after implementing and testing the pulsar fold-mode profile data fitting.

scatfit works well on pulsar fold-mode data now. I tested the code on data from several radio telescopes (MeerKAT, NenuFAR, and uGMRT).

• Various other documentation improvements.
• Documented how to fit pulsar and FRB data.
• Mentioned the data formats supported.
• Added code to correctly load pre-dedispersed data, such as from a single-pulse pipeline.
• Added code to correctly load full-polarisation data.
• Added a --norfi command line option to skip all internal RFI excision methods. This is useful for pre-cleaned data.
• Improvements to the output plots.
• Tweaked the plots and output for low-frequency NenuFAR data.
• Performed significant verification of the code on data from several radio telescopes.
• Made the code sideband order agnostic. It flips the band, if required.
• Edits so archive.py handles tsamp and freqs correctly by @jamesdturner in #3
• Described what to do for voltage data.
• Explained how to determine a scattering-corrected DM reliably.

v0.2.23

Software after adding the PSRCHIVE loader class and various smaller tweaks.

• Switched to own forks for some of the dependencies until the issues can be fixed upstream.

• Cleanup of the code.
• Reading PSRCHIVE files and new overview plots by @InesPM in #1.
• Added the NenuFAR telescope as a simulation target to simpulse.
• Improved the integer quantization code in simpulse.

v0.2.21

Software after adding Readthedocs online documentation and CI/CD actions to build and deploy manylinux platform wheels on the PyPI software index.

• Switched to Cython 3.0.0 release.
• Added GitHub Action to build manylinux platform wheels on demand.
• Moved CI/CD actions into reusable workflows.
• Added Sphinx-generated documentation on Readthedocs.

Full Changelog: v0.2.20...v0.2.21

v0.2.20

Software after improvements to the pulse simulation code.

• Added NenuFAR simulation target.
• Added commandline switch to let the user select the data included in the fit.
• Switched to pytest test runner.
• Added CI tests using GitHub Actions.
• Correctly simulate intrachannel dispersive smearing in the simpulse code.
• Various other small tweaks.

Full Changelog: v0.2.19...v0.2.20

v0.2.19

Code after adding scatfit to the PyPI software index.

Changes:

• You can now install scatfit by running: pip install scatfit.
• Various improvements to the output plots.
• Updated citation files and link to the now published paper.
• Several other minor tweaks.

Full Changelog: v0.2.18...v0.2.19

v0.2.17

• Added example plots.
• Implemented a true band-integrated profile model.
• Implemented the most important profile models using Cython, resulting in a ~1.8x speed improvement over the pure Python/Numpy implementations.
• Improved the processing speed considerably.
• Added regression tests to ensure that the Cython and Python/Numpy implementations are numerically identical.
• Switched to a standard exponentially-modified Gaussian function as profile model as default.
• Referred to the exponentially-modified Gaussian model as 'analytical' model.
• Added a short FAQ section.
• Tweaked output plots.

This software version was extensively verified using fake and MeerTRAP filterbank data.
