Each mark is one record; bars are stated ranges, whiskers stated uncertainties. Filled marks: P, P-comp, P-db; hollow: S, V, C, P(abs). Hover a mark for its source. Each row has its own axis; no mean or fit is drawn. Rotate any record into a cut: tensors and frame conventions.

Weis & Gaylord 1985 lists these signed p14, p41 < 0 next to Smith & Welsh c14 > 0 in its IRE frame, without stating Avakyants' own frame; the sign pairing stays open until Avakyants 1976 is read.
