By finding and subtracting the baseline, we can make the peak finding on data easier and more accurate. This function automatically creates a baseline for spetrum data.
When Origin computes the baseline, the Auto Threshold variable is used to set the threshold of curvature of the baseline. And you can use the Anchors variable to set the number of the anchor points, which can be used to adjust the shape of the baseline.
The X-Function scans the curve data for sections whose curvatures are less than the threshold (determined by the Auto Threshold variable). These sections are then used to compose the baseline.
