Delta(3-5-7) Changes
Subject

 Conclusions
 Comments
Optimization of efficiency vs d357
 Done
 -Delta(3-5-7) < 25 is in the plateau, efficiency (full luminosity range) drops by about 0.5% when going to SL3 mask only, efficiency vs Delta(3-5-7) shape stays the same for high luminosity

of Efficiency
 Done
 Stable, both in magnitude and slope for a set of matching requirements similar to the default one. We should continue to use the default.
 This is what we want.
