30 Degree Long sqrt(N) Test
Obtain 10 exposures (dithered) about each center for 30 degrees
Along Stripe 82, following preRigidGrid-v3 footprint
Test √N and how rigidity of a length of PreCam observations
Standard PreCam exposures
(g,r,i,z,y) = (36 51 65 162 73) = 387+5*20 = 487 seconds.
Call it 10 minutes/position, 260 positions total = 43 hours
with standards, 51 hours
=> 6 nights w/o weather.
Do-able inside our 2 weeks, modulo the moon.
Standard PreCam standard star observations
The usual set of standard star fields, 3 fields/hour
26 centers along Stripe 82
for each center, 10 observations in a dither-slither format
implemented as tilings, different tiling numbers for photometric, non-photometric
positions and exposure times provided by PreCam ObsTac
Full moon is Sept 8 2010. New moon is Sept 23.
do i,z,y first. Move to g,r as moon conditions permit.
