refcalc-fd.out and refcalc-amp.out

TensErLEED writes the output of the Reference calculation for each energy step, i.e., the diffraction intensity \(I\) and complex amplitude \(A\) of each requested beam (index \((h|k)\)) at energy \(E\) to two files called fd.out and amp.out.

In a first step, ViPErLEED takes these outputs and combines them in the files refcalc-fd.out and refcalc-amp.out. These files thus contain the raw, unformatted output of the reference calculation. They are provided primarily for compatibility and debugging purposes.

The same data is provided in a more readable and useful format in the THEOBEAMS.csv file.
