“…measurements, mainly transient field method. The previously measured g factors are labeled as "Sh81 TF" [21], "Gr85 TF" [22], "Th85 TF" [24], "Du88 IPAC" [23], "Du88 TF" [23], "St07 TF" [17], "St07 RIV" [8], "St05 RIV" [19] and "Be08 TF" [20]. In panels (b), (c), and (d), the family of curves for a certain G k represents the average value (black) and the uncertainties in τ (red).…”
