That's true. But I thought that you measured the mode after those optics and the effect of them is already included.
So:
- We need to model the transmissive optics in order to understand the measured mode which is different from the MC mode slightly.
- We just can calculate the modes based on the measurement in order to figure out the realistic positions of the MMT1 and MMT2.

Rana pointed out that the anticipated mode calculation should be modified to include the index of refraction of the crystals in the Faraday, and the polarizers in the Faraday. This may affect where we should put MMT1, and so this should be completed before round 2 measurements are taken, so that we can move MMT1.
