Tuesday notes, System Architecture Mtg July 10, 2007 Notes by Claire Max Afternoon: What should Architectures five and six be? (Three and four are Keck 1 upgrades, and Indian Wells design) Claire's thoughts: 5) Precision MCAO (2 relays) + dNIRI 6) dNIRI operates independently of narrow field instruments (on another Nasmyth platform, same telescope; or on the other telescope if lasers can be located between the two telescopes and free-space propagated to either telescope)
