Beam calibration procedure:
===========================

1) get the data files with FC data

2) from each file choose 5-10 similar numbers from the first column
and find the average of those for each run.

3) use scl2txt to get the table for the runs you did above,
the fields that one needs are TA.BAF TA.NAI and clock.free.

4) merge the table in 3) with the data in 2) in excel.

5) add 3 more columns with TA.BAF/clock.free; TA.NAI/clock.free and
FCx10^9.

6) add a 'target' column and sort your data by a target

7) graph (BAF/cf vs. FCx10^9) and (NAI/cf vs. FCx10^9), use log scale
if appropriate.
