2. Large telescopes Main issue is baffles & shields. Do we need a fixed and shield?
ACTION ITEM: Add figures of sidelobes from Pato’s SPIE paper.

Explain why SO didn't pursue a 19-tube cryostat. ACTION ITEM: Ningfeng to provide a few sentences about challenges associated with scaling 13-tube to 19-tube cryostats.
Steve points out that rhomboidal detector shapes were a big surprise from the Princeton meeting. Detector team is looking into costing this.
Do we need to dig into details of noise calculations in this section?
ACTION ITEM: Mike to confirm that noise Tiger team is going to describe noise performance of LATs, which means we only need to report the detector numbers.
ACTION ITEM: Abby to check with detector costing team whether the increase in LAT detector count is a large enough cost increase to be problematic.
4. How do we wrap up the writing?
ACTION ITEM: Jeff to work on cold optics text.
ACTION ITEM: Mike to finish telescope optics design text.
