SoFT v2.1

Refactor tabulation_parallel for robustness and performance

• Input validation

  • Added global pre-check ensuring all assoc (files) and data (filesB) FITS files have matching shapes.
  • Added per-frame shape check inside process_file for extra safety.

• Robust handling of masked/invalid data

  • Convert FITS MaskedArray inputs to np.nan-filled float arrays.
  • Restrict centroid (X, Y) and flux calculations to finite pixels only.
  • Skip blobs with no finite data or zero flux; issue warnings.warn to aid debugging.

• Centroid and eccentricity fixes

  • Prevent NaN propagation in centroid numerators/denominators.
  • Ensure ecc is only computed for valid blobs.

• Performance improvements

  • Replaced repeated DataFrame concatenation inside loops with list-of-dicts → DataFrame.from_records.
  • Guaranteed native float/int storage in per-blob records (avoids mixed dtypes).

• Trajectory consistency

  • Sort grouped blobs by frame before applying consecutiveness checks.
  • Raise informative errors if frame sequence or labels are inconsistent.

• Velocity computation

  • Handle non-finite trajectories gracefully: emit warning and fill with NaN velocity arrays instead of failing.
