Minutes
We discussed the basic architectural options for the OIWFS
Strategy is to evaluate the performance vs. sky coverage for a 'one-side', no-incursion, external-to-the-dewar patrolling sensor (similar to IRIS OIWFS), and then address any performance shortfall if necessary
Rich will engage with Brent and Co. to get this started by Dec 2 (hopefully), but in practice this will depend on the weather at Palomar summit
Possible avenues for larger sky coverage if needed:
Allow some incursion into spectroscopic FoV (probably diminishing gains because an external patroller is so far from focal plane)
'Two-sided' dual OIWFS to patrol each side without incursion
Focus sensing strategy may impact performance as well (e.g. 2x2 SH WFS v. pyramid v. separate (slower) focus sensor(s))
Meeting schedule
The next IRMS team meeting will be in 2 weeks: Tuesday, Dec 13 at 9a.
Outstanding Actions
Rich to work with TMTO (Brent) to assess suitability of external OIWFS in terms of sky coverage and performance (by Dec 2)
Rich to make written request to WMKO (Sean) to support MOSFIRE cost detail in support of the IRMS estimate (by Dec 15)
Rich to contact UCLA (Ian) to request UCLA detail MOSFIRE cost breakdown (by Dec 10)
