Hi all,
Last night I've try using the EOCA scenario provide by Christophe some P52 using the preferred option and the Ops3 REFSMMAT.
Everything is working well, but when the CMC drive optics to find the select star I found it orizzontally match the cross in the SCT but vertically placed at the top of the SCT.
I've centered with the SCT and mark the star using SXT.
The result of the two star mark is a poor +01598

This mean the the IMU is out of his alignment or that I've made something wrong in the mark procedure ?
How to realing the IMU in the best way ?
