      Description

      The rotation in the CWFS sensors in ts_wep is the wrong direction so the R04 and R40 sensors are 180 degrees off when estimating Zernikes.

          When using the original code and running the closed loop at high density of the wavefront sensors with 10 iterations the loop does not converge:

          Some more evidence that this rotation change is correct comes from rerunning our data from https://github.com/lsst-ts/ts_analysis_notebooks/blob/develop/aos/aos_milestones/lsstCwfsPipeline.ipynb.

           

          We can see that the new version (2.3.6) of ts_wep aligns better with the OPD values.
