V2.99 simulations description

“draft_connected_v2.99_10yrs.db”
This is a 2 band 0.9 strength rolling cadence (but starts after a full 1.5 years, so not “early”).
There are long gap triplets every 6 nights, and revisits within 0-2 hours are suppressed (at the lowest strength).
The twilight NEO microsurvey is added starting year 1, using riz filters and 4 repeats per night, and active every 4th night.
The galactic plane footprint is based on the TVS/SLWMV priority map, modified to reduce isolated areas.
The galactic plane filter balance is very red.
The NES weight has been lowered slightly from baseline.
The DDF visits make up about 7.5% of the total visits, with COSMOS acquiring ~double depth (10yr depth by year 3, then continuing at the standard cadence for the remainder of the survey). The DDF strategy is a fairly simple pre-scheduled season.
“dd6_v2.99_10yrs.db”
This is similar to the above simulation, but reduces the fraction of time spent on the DDFs to 5% total. The reduction is implemented uniformly across all of the DDFs.
“low_gp_v2.99_10yrs.db”
Again, similar to the draft_connected simulation, but the weight of the footprint within the galactic plane WFD area is strongly reduced, which reduces the number of visits in the galactic plane ‘high cadence’ (WFD-level) area.
“roll_early_v2.99_10yrs.db”
This is similar to the draft_connected simulation, except in some areas related to cadence.
The 2-band rolling cadence starts “early”. In addition the repeat weight is stronger.
