Filler Programs

There are opportunities for so-called “filler” programs on all telescopes. Observing programs that exploit frequencies below 10 GHz, do not have scheduling constraints, and could benefit from short scheduling blocks are eligible to be considered for “filler” time. The proposal should make clear in the abstract and in the science justification that “filler” time is being requested. If “filler” time is requested, the proposal will be ineligible for scheduling priority A or B. A proposal requesting filler time should not require fixed time or guaranteed monitoring periods.
