Method

• Hot and cold cases come from the worst released thermal robustness cases for this design signature.
• Launch-relaxed alignment maps the released support deflection proxy onto a residual alignment case using the structural launch-restraint-release allocation of 15.000 um.
• Equivalent WFE proxy is the case budget multiplied by the largest normalized image-quality utilization across blur growth, refocus, and chief-ray shift.
