By running this script (instruction here in README), we get:

Area under the histogram (number of surviving events):  2241.720458984375
Bin content:  2241.720458984375  error =  26.004912373817632
Expected events:  8.134295648868406  +/-  0.09436129501507277 events

And we get this efficiency histogram that is identical to the one in the paper:

And the passed number of events histogram:

From the histogram we have 7879 accepted events out of 20,000. Thus we have acceptance of 0.394 (the paper had 0.36 for the acceptance)

The yield is 2241.720458984375/20000= 0.112086, which is compared to the yield from the paper.

In the paper, the fraction of surviving events for the 0.1 ns 400-GeV smuons is:

acceptance X efficiency = 0.36 * 0.355 = 0.1278
