I took some more recent data and ran it through my code to make these measurements and I'm very happy with the results. I made a small modification to the peak finding code that made a huge difference in terms of positive detections.
Anyhow, the latest measurements are from data taken in 'Sit and Stare' mode on 2014-09-19 05:17:12-07:14:54. This calibrated data is marked 'OBS 3860608353' and is available here.
My measurements are here, which is a zip file containing the data values.
