- Notes and Changes:
- Changes from E080512 are in the "Applicable Documents", and the "Fabricate From" indicating that we will start with a finished ETM and re-polish.
Inclusion of variances that were approved during the previous fabrication epoch;
C0900456 approval of 150W inspection source. C1102248 Change in calculation of RMS surface roughness, to include sleeks - rather than have the sleeks count as scratches (sleeks, by definition, have very small surface height 1064 nm) See also C1000393 C1000216 Allowable Barrel Defects
