Questions/tasks

Look at the fitted peak values (Omar, Sho)

Extract preliminary absolute calibration from peak

Is the peak width as expected?

25keV peak at 5% intensity; can we see that (noise is ~3keV)?

Estimate number of signal events in peak?

Can we see any signs of 88keV? Based on suppression and the signal events in 22keV peak?

How long would we need to run to get 100 88keV events?
