provides valuable information on obvious structure 71 in a fit. In this particular scenario, the straight line has a positive increase from 7105 to 7130 eV, which implies that the mean of residual is not zero and dominant and oscillating structure is visible in the area of pre-and rising-edge (~7110-7120 eV). On the lower plot, the raw data is depicted by a blue line, while the fit model is represented by a dark blue dashed line. Additionally, dotted colored lines ranging from dark to light red are shown to represent individual contributions. The colors utilized in this visualization are generated by Seaborn's rocket color palette. Adapted from Ref. ; Copyright 2023 America Chemical Society (ACS).
