---|---|---|
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. |
