I inserted the lucite target and looked at the image with the filter taken out. The slit image looked rotated a bit CCW from what looked vertical. Tried rotating the detector to that approximate alignment but got the same sort of waveforms. I tried swapping the P detector with another unit, (#6) and after balancing and adjusting the offset for that detector, I got the same sort of waveform. I have come to the conclusion that there is no problem with the detector as I suspected at one time. There must be an alignment problem in the optics somewhere.
