PEMpro 02032017 5

With the fit to the residual error, I created a refined PEC model and uploaded to the mount. Be sure to sync before uploading any PEC curve to the mount to avoid phase shifts. I then collected data with PEC on using this refined PEC curve. The data from the refined curve showed error to the correction at 6:00 and a fair amount of low frequency oscillations: These uncorrected error regions were from where there was the most variation in the zeroth order data.
