On the call: Steve, Nils, Mike, Akito, Toki, Adrian, John,

Adrian thinks that for the Tuesday telescope size discussion people will be separated randomly into different groups. Goal is to seed discussion.

Big question to address is what will people need to see to consider using only large aperture telescopes.

Discussion of systematics and agreement that further sidelobe studies are needed. Clipping sidelobe is particularly important to study. It's not yet clear whether e.g. cross-Dragone vs. off-axis Gregorians have better performance.
