PyZebArdYolo 1.3.2

Corrects the imaging scale used to express localization errors in millimetres.
No change to the acquisition software, firmware, data or any result reported in pixels.

Fixed

• Imaging scale corrected from 1.24 to 2.39 px/mm (1 px ≈ 0.42 mm). The previous value
  assumed a 560-mm arena; the internal length of the arena is 350 mm (hardware/arena/).
  Only the millimetre equivalents change (median radial error of PyZebArdYolo ≈ 4.2 mm).
  Updated in validation/analysis/03_agreement_summary.py, validation/README.md and
  validation/analysis/results/localization_summary.csv.

Changed

• validation/analysis/02_mixed_model.R also reports the variance components of the
  method-comparison model (results/mixed_model.txt).
• Version metadata (CITATION.cff, pyproject.toml) set to 1.3.2.
