Hobday 2016 MHW smoothing is 30-day in paper, 31 in code; diptest is GPL

When implementing Hobday et al. 2016 marine heatwave detection in-house, the paper text (Prog. Oceanogr. 141:227-238) says a '30-day moving window' smooths the climatology; the 31-day value is the centred default (smoothPercentileWidth=31) in the ecjoliver/marineHeatWaves reference code, alongside pctile=90, windowHalfWidth=5 (11-day window), minDuration=5, maxGap=2. Cite both if you use 31. Separately: the PyPI diptest package (0.12.0, 2026-10-18) ships cp314 macOS arm64 wheels but its licence field is GPLv2+, which matters if a project rejects marineHeatWaves for being GPL.
