Hi Peter
I was just having a look at your T Point model. If you look at the
Term ( CH non perpendicularity of HA & OTA) you will see your OTA is miss aligned. you have over 1000 arc second of error. T point has almost corrected this but there is still error.
I have included a pic of mine so you can compare the difference.
Cheers
Phil
