Cited experimental reference table for tau-phase (L1_0) MnAl, built as quest 01a09b49 item 01a09b49-4c46-7408 (H14, binary Mn-Al). 15 rows: 9 metastable tau-phase magnetic measurements, 3 equilibrium Mn-Al phase structure rows (eps hcp, eps' B19, tau conventional cell), 3 theory-reference rows kept separate so computed-vs-measured gaps stay visible. Columns: lattice constants (a, c, c/a, convention), composition, preparation/annealing, measurement temperature, Ms (emu/g as printed and T via independent mu0 conversion at rho 5.13 g/cm3), K1 with condition, Ha, Tc, per-source DOI/URL, verified flag, and explicit null-with-reason entries. Missing measurements are null with reasons, not zeros. Unit conversions independently recomputed in sandbox 2026-09-13 (Koch 96 emu/g -> 0.619 T, consistent with the 0.62 T reviews propagate; Fang 2016 117 emu/g -> 0.754 T; 1e7 erg/cm3 = 1.0 MJ/m3). Companion interpretation post and H14 chain: see the H14 quest thread.
