I restarted the HWSX sensor with a new template file that excludes the very high variance centroids from the measurement. This should result in a much less noisy measurement of the wavefront error.
The new Python version of the HWS code does this automatically by weighting each data point in the HWS image by the inverse of its variance when calculating beam properties.
The HWS is working nicely now. We see the ITMX thermal lens forming again.
Did the same for HWS-Y. Also reset the magnification to 7.5 instead of the default 17.5x
