Notes. Mean αOX and log U with their corresponding standard deviations of the distributions calculated by HCM-TEFF-IR for the studied sample under different assumed conditions in the models. Besides the values for the overall distribution (m), two values (m1 and m2) are given assuming a bimodal distribution, adopting a GMM, and applying a Shapiro-Wilk test so that a p-value lower than 5% for each component confirms the bimodal hypothesis.
