1.4.2.2. - Merging Scans and Background Subtraction
The default
+s option causes the data points from all the scans read in to be sorted
by
x
values and data points with the same
x
value averaged.
If data is to be normalized and/or error bars calculated,
the appropriate weight is given to the count time for each point.
Scan numbers that end with the letter
b are used as background scans.
The sort-and-merge flag should be in effect when using background scans.
Entering
fn . 12b 13 14b 15b 16 17bfor example, or
fn . 13-15 16-27bwill merge the data from the background scans with the data scans, subtracting the background counts from the data counts at each x value. When doing merging and background subtraction, the x values must be identical for the data points to be merged.
