… stores

open_altimeter / altimeter_near / altimeter_passes work on both kinds of cell-indexed store: the SWOT index has a leading month dimension (months outside the time window are skipped), and its columns come back with the common names (hs, dist2coast, flag = 1 where swh_karin_qual == 0, else 4). With a small radius the pass median is the patch median validated against buoys. Tests with a synthetic two-month SWOT store; tried on the real stores (IMOS DM00 near Santander: 4,636 passes 1985-2026; SWOT: 199 passes).
