- We have started studying the TWE map for the spare ETMX. Measurements at 0 and 180 degrees are missing. We are considering constructing maps for 0 and 180 degrees from measurements at other degrees (45, 90, 135, 225, 270 and 315 degrees).
- We think that map(0)+map(90)=map(45)+map(135). We studied TWE maps for ITMs to check if this relation is correct. As ITMs are correctively polished using circular polarized beam, the sum of map(0) and map(45) should be close to zero. This also should work for the sum of map(45) and map(135). However, we found that the sum is not zero.
