<p>Hello!<\/p><p><span style=”text-decoration: underline;”>Preamble<\/span>: I am using a tolerance script which calls a merit function (MF) that is optimizng for RMS wavefront error (WFE). Among others, there is an operand RWCE for WFE in that MF with weight 0.000. I have a whole tolerance table as usual, and some run-of-the-mill compensators in my script. At the end of the script, I report RWCE, which by manual inspection appears to be a reasonable and correct number. <\/p><p>In my tolerance report, in the Sensitivity Analysis and the Monte Carlo simulation, I am getting two things: My WFE value from the RWCE operand as expected when using the REPORT<\/em> command in my script, and also the “Nominal Criterion” which is the literal merit function value since I am using a user-defined script. For me, the WFE is the actual useful thing for real life assessment of the system. <\/p><p><span style=”text-decoration: underline;”>Here is my question:<\/span> It is well and good that my report lists the WFE for each tolerance extreme in the Sensitivity analysis and each Monte Carlo output because I can read it manually and make sure I am within my performance constraints. However, what I really want is the summaries<\/strong> (see two screenshots) for the Sensivity analysis and the Monte Carlo analysis to be in WFE, not merit function value. <\/p><p>If I were to not use a user-defined script, I’m aware I could select any criterion I want as the “nominal criterion” from the Criterion menu of the Tolerancing function. However, I have to use a script because I need to define tilt as compensators using CPAR and my tolerance data editor flips out if I try to use CPAR there.<\/p><p>Thank you very much.<\/p><p><span style=”text-decoration: underline;”>Attachments:<\/span><\/p><p>sensitivity-summary<\/em>: Sensitivity analysis summary which is reporting the merit function.
