Criteria for determination of the quantity of TGC peaks*.

*The first row displays the ranges of coefficients of correlation between the TGC and the two- or one-peak fitting (R2 and R1, respectively) and the ranges of the R2/R1 ratio for 19 TGCs known to contain one peak. The second row shows the same parameters for 30 curves known to contain two peaks.

第一行展示了19个已知为单峰的TGC的相关参数：包括其与双峰拟合（对应R2）、单峰拟合（对应R1）的相关系数取值范围，以及R2/R1比值的取值范围。第二行则展示了30条已知为双峰的曲线的上述同类参数。
