SCINTOOLS (SCINtillation TOOLS) is a package for the analysis and simulation of pulsar scintillation data. This code can be used for: processing observed dynamic spectra, computing secondary spectra and ACFs, measuring scintillation arcs, simulating dynamic spectra, and modelling pulsar transverse velocities through scintillation arcs or diffractive timescales.

• This is currently considered a pre-release only
