From Santiago: when activating the ‘history columns plot’, I noticed the program plots all columns regardless of they being flagged as valid or not. I suppose it would be enough with reading the value for ‘isgoodpoint’ in the evaluation-log to select the valid columns only for plotting. Evaluation of noisy spectra usually result in columns which may be a few tens of ppmm, obviously with large fit error and flagged as ‘0’ for the ‘isgoodpoint’ parameter, but they get plotted anyway and may give the wrong impression that the volcano has emissions above background.
