Scattering Fits

FLITS exposes an optional fitburst-backed scattering workflow.

Dependency model

The fitting tab is available only when fitburst is installed. This dependency is optional and must currently be installed separately from the main PyPI package:

pip install "fitburst @ https://github.com/CHIMEFRB/fitburst/archive/3c76da8f9e3ec7bc21951ce1b4a26a0255096b69.tar.gz"

What FLITS passes to fitburst

The adapter uses the current session state:

• selected frequency band
• current crop
• event window
• current mask
• off-pulse normalization

It fits only the selected event window and returns structured success or failure results instead of hard import-time failures.

How to use the results

Treat these outputs as model-based diagnostics:

• intrinsic component width
• scattering timescale
• parameter uncertainties
• fit diagnostics

They are useful cross-checks, but they should be interpreted alongside the non-parametric measurements and temporal diagnostics rather than as a complete replacement for them.
