“Early Science” as “verifiers”, planets pretty good (known structure, known flux density, known lines, etc…) also decent candidates for early science feeling is that instrument definitely has to be fully debugged before “early science” undertaken

Questionnaire importance and/or science case for ACA? important for all major planets (save Neptune), as they are large and have lots of flux density and structure on the large scales also for comets, which, although they have less flux density, can be very large and have lots of complicated large-scale structure also for debris disks, which might be more similar to comets

Questionnaire ranking of “non-baseline-project” bands: Band 1 (31.3 - 45 GHz) -- important for probing below the diurnal temperature wave on solid-body planets, and deeper into atmospheres. Some planets spend significant amount of time in southern hemisphere, so assuming EVLA will do this is not enough. Band 10 (787 - 950 GHz) -- important for the added resolution, and line strength. Band 5 (163 - 211 GHz) -- potentially important for observations of the 183 GHz H2O line. Bands 2 & 4

Questionnaire Science Center listed functions, although considered quite vague in some instances, seem mostly appropriate. Biggest concern is not maintaining good contact path between observatory (mostly staff), and community. “Feedforward” considered nearly as important as “feedback.” A more important exercise, not listed as part of the questionnaire, might be to rank the listed functions.
