FLITS
FLITS, the Fast-Look Interactive Transient Suite, is browser-based software for
interactive FRB burst analysis. It brings burst inspection, masking,
measurement, DM optimization, temporal/spectral diagnostics, optional
model-based fitting, and export into one workflow-oriented tool. Input
formats include SIGPROC filterbank (.fil), search-mode PSRFITS
(.fits, .sf), and CHIME/FRB HDF5 (.h5, .hdf5) including public
catalog waterfalls and beamformed BBData power files, extensible via a
plugin-based reader framework.
What FLITS is good at
- Loading local SIGPROC, PSRFITS, or CHIME/FRB HDF5 files into a browser-based analysis session.
- Interactively defining crop windows, event windows, off-pulse regions, and spectral windows.
- Masking problematic channels before running measurements.
- Reporting burst measurements together with provenance and exportable state.
- Comparing DM metrics and inspecting residual arrival-time diagnostics.
- Running temporal-structure and spectral analyses on the current selection.
- Exporting structured results, plots, and session snapshots.
Quickstart
Then open http://127.0.0.1:8123.
If you want the optional fitburst-backed scattering workflow as well:
pip install "fitburst @ https://github.com/CHIMEFRB/fitburst/archive/3c76da8f9e3ec7bc21951ce1b4a26a0255096b69.tar.gz"
Start here
- Use Quickstart if you want the shortest path from install to first session.
- Use Installation and Deployment if you need Docker, Apptainer, or remote/HPC usage.
- Use Session Workflow once the interface is open and you want to know how to work through a burst.
- See Supported Formats for the full reader matrix and detection rules.
