Hi Nick.? To use PECPrep, you need to give it 'clean' unguided data as the file you gave it has multiple sections, and to be honest I'm not sure what its analyzing when you open the file as is.? To create a clean file, do your calibration in PHD2, shut down the program, then re-start.? Go into the brain (Advanced Settings) and uncheck the box 'Enable mount guide output'.? Then go back and start 'Guiding' - no guide corrections will be sent to the mount but the star positions will be logged to be used in PECPrep.? After finishing the section, close PHD2 and rename the file accordingly.
That said, I edited your log file to include only unguided portion of log section 5 and fed into PECPrep, and got the attached results (about 15" peak to peak, with the 76s error at about 3").
An easier way is to open the log file in the PHD log viewer, select section 5, right-click on the graph and select 'Analyze unguided section'. This tells about the same story, except the displayed values are amplitudes and not peak to peak (so half of what PECPrep displays).
Yet a third way is to open the file in the PEMPro log viewer and select that section (now labeled section 4 since it doesn't include calibration sections, and it also says Guided=True since that section started out with a few guide commands before being disabled).? Again, similar results.
