Paramount ME Periodic Error

I just spent a nice cold night out measuring the Periodic Error on my Paramount ME and can say I’m very happy

Assuming I did everything correct I measured my PE at +1.1/-1.5 or just shy of 3 arc/sec peak to peak (2.6arc/sec) and PemPro Shows it can get this down to +0.4/-0.5 arc/sec

I measured for 12 Work Cycles with 1 second exposuser on my AT10RC with a STL-11000M2 Camera MaximDL was driving the Camera and of course TheSkyX the Mount.
