YuuPo Analysis Platform
YuuPo Analysis Platform
A magnetic-field analysis server for MVA, FFT-bin wave-direction diagnostics, SVD spectral checks, and report-ready quality comparison.
Analysis Setup
Map the uploaded table, confirm roles, choose MVA or SVD, then open the matching workspace.
Selected files
Preview up to three files concurrently. Each file keeps its own mapping, timebase, units, nickname, and error state.
Choose one or more files. Mapping is applied only to files with an identical column signature.
Select a data file, then preview it here before creating an analysis session.
Column auto detection + manual confirmation
Every column remains editable. High-confidence suggestions are preselected; medium and unresolved columns must be checked.
Raw upload preserved unchanged.
Multi-file time alignment
Map each file independently, choose the magnetic-field session as the primary timeline, then align electric-field and auxiliary sources without modifying raw uploads.
Complete column mapping for at least two files.
Frequency-bin MVA / FFT-based MVA
- For wave direction analysis, run FFT-bin reconstruction before covariance/eigen MVA.
- Time-domain MVA remains a broadband diagnostic.
Magnetic-only SVD/MVA cannot determine a unique propagation sign.Magnetic-only result is sign-ambiguous and is not a unique propagation direction.
Current Analysis: SVD
Spectral SVD / Wave Analysis
Magnetic-only spectral analysis cannot determine a unique propagation sign.
Current Method: SVD
Magnetic-only SVD/MVA cannot determine a unique propagation sign.Magnetic-only result is sign-ambiguous and is not a unique propagation direction.
MVA workspace overview
Use the workspace tabs to keep the main analysis surfaces short while the sidebar keeps upload, range, processing, and run controls available.
Global controls
Upload, selected range, processing, MVA, spectrum, spectrogram, report, and status controls stay in the left panel.
Analysis outputs
B(t), MVA / Geometry, Frequency / Spectrogram, Report / LLM, and Debug outputs are separated into main-content workspaces.
Preserved behavior
Backend APIs, scientific calculations, preprocessing defaults, API-key handling, and raw debug payloads are unchanged.
No8 compatibility validation
One-click validation runner for the currently loaded No8 reference dataset. Applies fixed settings and runs existing analysis APIs.
Load a No8 reference dataset first.
Fixed No8 validation profile
Phase 1: sample-index fs=256 Hz, Wave Angle df=0.5 Hz, 512 samples, 2 s block
Phase 2: Wave Angle df=0.25 Hz, 1024 samples, Spectrogram 1024/512/2048, ellipticity 1024/512, 0-0.4 Hz
Validation/diagnostic outputs only. Raw data, preprocessing, MVA, Wave Angle, ridge, r12/r23, and ellipticity algorithms are not modified.
B(t)

Load timing will appear after data is selected.

YuuPo Production FFT-bin MVA
Runs the YuuPo production FFT-bin MVA core: detrend, Hann + FFT, isolate a frequency bin, inverse-FFT reconstruct the component, then covariance/eigen MVA.
No FFT-bin MVA result yet.
Magnetic-only SVD/MVA cannot determine a unique propagation sign.Magnetic-only result is sign-ambiguous and is not a unique propagation direction.
Run YuuPo production FFT-bin MVA diagnostics from this panel.
min r23=0; min vector power ratio=0; skip DC/Nyquist
No FFT-bin MVA run yet. Set fs, df, frequency/ridge mode, then run.
FFT-bin MVA angle trend
Run FFT-bin MVA to show wave angle by window.
FFT-bin MVA 3D direction path
Run FFT-bin MVA and select a valid row to show the diagnostic path.
x
Use the delta-B hodogram for sample-order path playback. Normal-axis modes are discrete diagnostics.

IDL-compatible Validation / Angle Difference
Compares YuuPo production FFT-bin MVA against the built-in No8 IDL-compatible reference when the current dataset and fs/df match the validation profile.
No production-vs-IDL comparison has been produced yet. Run YuuPo production FFT-bin MVA first.
Plot uses matched windows at the selected frequency; stable-bin metrics summarize all non-DC/non-Nyquist bins. Difference: YuuPo production - IDL.
time-domain MVA minimum variance axis
Time-domain MVA is a broadband diagnostic and may not match the IDL-compatible frequency-domain wave-angle workflow.

Quality / Comparison
MVA quality review keeps FFT-bin diagnostics and time-domain diagnostic checks visibly separate.
FFT-bin MVA
Review selected frequency bin, r12/r23, vector power, skipped reason, and sign ambiguity from the YuuPo production diagnostic rows.
Time-domain MVA diagnostic
Use broadband sliding-window MVA only as a secondary diagnostic and comparison surface.
