#### Description

• Turn off all perturbations in (ts_)phosim.
• Simulate a single star exactly on the boresight.
• Estimate Zernikes.  You should find that only Z4, Z11, Z22 are non-zero.
• Repeat for different rotations (shouldn’t matter if you tweak rotTelPos or rotSkyPos).  You should find that all the Zernikes here are independent of the rotation angle.  I.e., the ones that start out at zero are still zero, and the others are constant with rotation angle.

Conducted that test in a notebook here https://github.com/suberlak/AOS/blob/main/AOS_DM-34065_rotation_JM_test-01.ipynb using parts of CloseLoopTask , but turning off  mirror, lens perturbations via teleFacade.addSubsys. While I do not find that only Z4,Z11,Z22 are nonzero (in fact, Z6,Z19,Z21  have highest value), their value for a star directly on the boresight does not depend on the rotation angle at all.
