I maintain a software tool called scatfit, which I designed and implemented in 2022 to perform scattering fits of very low-S/N fast radio burst (FRB) data. Its primary aim is to measure the scatter broadening incurred by a radio signal (impulse) as it traverses various Galactic and extragalactic turbulent ionised media. scatfit measures both the scatter broadening time and its power law dependence on radio frequency, the so-called scattering index. It also determines the scattering-corrected dispersion measure of the received signal.

We had a bit of a breakthrough last week thanks to the people at the University of Manchester, notably James and Ines. My scatfit software works fine on NenuFAR data and most other folded pulsar data now!

After the breakthrough last week, I added various other pulsar fold-mode-related functionalities and tested scatfit systematically on a large variety of FRB and pulsar data from various telescopes (MeerKAT, NenuFAR, GMRT, and LOFAR). The software now supports the vast majority of pulsar and FRB data formats. Additionally, I significantly extended and improved its documentation.

I have tagged a new version, v0.3.0, that incorporates all the improvements. Please see the release notes and update your local installation.
