double  asymmetry_factor 
The asymmetry factor is a measure of peak tailing. It is defined as the distance from the center line of the peak to the back slope divided by the distance from the center line of the peak to the front slope, with all measurements made at 10% of the maximum peak height. asymmetry_factor = As = b/a where a is min width to peak maximum at 10% max peak height b is max width to peak maximum at 10% max peak height 
double  baseline_delta_2_height 
The change in baseline divided by the height is a way of comparing the influence of the change of baseline on the peak height. 
double  end_position_at_10 
The end position at which the intensity is 10% the peak's height. 
double  end_position_at_5 
The end position at which the intensity is 5% the peak's height. 
double  end_position_at_50 
The end position at which the intensity is 50% the peak's height. 
Int  points_across_baseline 
The number of points across the baseline. 
Int  points_across_half_height 
The number of points across half the peak's height. 
double  slope_of_baseline 
The slope of the baseline is a measure of slope change. It is approximated as the difference in baselines between the peak start and peak end. 
double  start_position_at_10 
The start position at which the intensity is 10% the peak's height. 
double  start_position_at_5 
The start position at which the intensity is 5% the peak's height. 
double  start_position_at_50 
The start position at which the intensity is 50% the peak's height. 
double  tailing_factor 
The tailing factor is a measure of peak tailing. It is defined as the distance from the front slope of the peak to the back slope divided by twice the distance from the center line of the peak to the front slope, with all measurements made at 5% of the maximum peak height. tailing_factor = Tf = W0.05/2a where W0.05 is peak width at 5% max peak height a = min width to peak maximum at 5% max peak height b = max width to peak maximum at 5% max peak height 0.9 < Tf < 1.2 front Tf < 0.9 tailing Tf > 1.2 
double  total_width 
The peak's total width. 
double  width_at_10 
The width of the peak at 10% the peak's height. 
double  width_at_5 
The width of the peak at 5% the peak's height. 
double  width_at_50 
The width of the peak at 50% the peak's height.
