sims_featureScheduler_runs1.5

v1.5 of simulations of the LSST scheduler

XXX--not final yet, will be anounced on community.lsst.org when released

Changes from v1.4

New defualt DDF behavior, limiting DDFs to about 5% of the total visits
Regions are selected to be more contiguous, reducing the mean slewtime
Eliminated extra filter changes in DDFs
Leaving the u filter mounted in the telescope for longer (until 40% lunar illumination)
No longer taking u+u pairs (only u+g or u+r)
Improved calculation of 5-sigma depth for variation between 1 and 2 snap visits
Set 5th deep drilling field to be a pair of Euclid pointings

DDFs

DDF strategies, including ones from the AGN and DESC white papers.

alt_roll_dust

Surveys where the WFD footprint is designed to avoid dusty regions. Includes version with rolling strategy and alt-sched North/South alternating strategy.

baseline

1 and 2 snap baseline strategies.

bulge

Covering the Milky Way bulge with different strategies.

daily_ddf

An initial attempt at having DDF fields observed daily.

dcr

An experiemnt looking at intentionally taking some observations at high airmass to help with DCR model construction as well as science enabled by measuring the DCR of objects.

filter_dist

Looking at different filter distributions (e.g., red or blue heavy footprints).

goodseeing

Ensuring the entire sky has an image taken in good seeing conditions every year.

greedy_footprint

Prevent the greedy survey at twilight from observing along the ecliptic. That should ensure the ecliptic is observed with blob pairs.

rolling

Various rolling cadence surveys.

short_exp

Covering the whole sky in short exposures.

spiders

Scheduling the camera rotator angle so that diffraction spikes are always along rows and columns.

third_obs

Dedicating the end of the night to re-observing areas that have been seen in the night.

twilight_neo

Using twilight time to look for NEOs.

u60

Increasing u-band visits to 60s.

var_exp

Using variable exposure times to make visit depths more uniform.

wfd_depth

Varying the amount of time in the WFD region.
