Issues for Optimizing Surveys

RFI management
- Characterization, test obs & algorithms, multibeam schemes (ALFA + other?)

Diffractive ISS

Þ multiple passes favored for low DM
n-t weighting for intermediate DM
no action for high DM

Refractive ISS

Þ multiple passes for low to intermediate DM

Nulling Þ multiple passes

“Search” vs. “confirmation”

Historically two different phases
PMB: candidate density Þ Tconfirm ~Tsearch
Þ do two “searches” = two passes on sky
