keyword=Spot++ on Optics. Reads Twice Size of on YThe figure below is spot++ test on optics target after MCC fix the magnet problem. The raster size we asked for is 3x4mm in MCC, and confirmed on oscillascope. However, the read back is very different from what we had before: it's now more like 2.5x4mm, twice larger in Y. We also confirmed the shape change on the BeO screen.
To be safe, a harp scan on both harps are requested. Then reducing raster size might be considered.
