After the initial work last year, I released a new version (v0.5.0) of my scatfit pulse profile modelling and fitting software for FRBs and pulsar pulses.
This is a major feature release that implements all functionality of a multi-component mode.
This allows one to simulate and fit bursts or pulses that consist of several individual profile sub-components. There is no limit on the number of components included in the model. The practical restrictions come from the quality of the input data and how well the MCMC can sample the larger parameter hyperspace. Using up to three profile components has been thoroughly tested.
Various metrics have been added to reliably estimate the dispersion measure (DM) from multi-component profile data.
Additionally, there have been significant feature additions in the pulse simulation part of the software. This includes simulating multiple pulse components and coherent dedispersion.
