Load a burst file to begin
Choose a file, set the dispersion measure, then work directly in the aligned viewer.
New Session Select a file and the DM to use when loading it.
Aligned Viewer
Top: time profile. Center: dynamic spectrum. Right: frequency profile.

Components
Exact Selection
Keyboard-accessible alternative to selecting coordinates directly in the plot.
Analysis Workspace
Stay in one live session and move from preparation through specialist analyses without losing the current burst state.
Prepare
Define the burst state, confirm readiness, and review compact measurement summaries before moving into specialist analysis tabs.
DM Optimization
Run a DM sweep with either integrated-event S/N or DMphase, inspect the selected metric curve, compare residual drift before and after, and review per-component DM estimates for complex bursts.
Model Fitting
Run a 2D model fit on the current selected event window, crop, mask, and spectral window.
Model Structure
Set component detection, then refine the generated initial guesses below.
Parameters to Fit
Core temporal terms are enabled by default; add propagation or spectral terms when the data support them.
Advanced Fit Setup
Temporal Structure
Measure the shortest statistically supported burst structure and inspect the fluctuation-frequency distribution with raw and averaged power spectra.
Rotation-Measure Synthesis
Import calibrated channelized Stokes Q/U spectra, configure the Faraday-depth search, and validate a dirty or RM-CLEAN result.
1. Load Q/U Spectrum
JSON arrays or a CSV table with frequency, Q, and U columns.
Required fields: freqs_mhz, stokes_q, and stokes_u. Uncertainties and channel width are strongly recommended.
2. Configure Synthesis
Blank grid values use wavelength-coverage defaults.
Export Results
Choose the outputs you actually need, inspect the exact artifact set, and then build the immutable bundle from the current session state.
Export Planner
Select structured outputs, arrays, and plots before generating the final bundle.
Plot Formats
PNG is enabled by default when plot export is selected; add SVG if you need vector output.
Window Formats
NPZ is the rich analysis bundle; FIL is the interchange export for downstream radio tools.
Window Resolution
Native exports full current-session bins; View follows the current time and frequency reduction.
Preview
Exact artifact rows and small plot previews for the current selection.
Last Built Bundle
The most recent immutable export snapshot, with final filenames and downloads.
