Create NEO optimized opsim runs #120

Open rhiannonlynne opened 9 years ago

rhiannonlynne commented 9 years ago

There are some alternative cadences we'd like to investigate:

0: Do NES in r band only (with WFD cadence - in 2/3/4 'pairs') [increase NEO completeness]

1: Sweet Spot survey - do sweet spot observations (60-90 degrees solar elongation) along ecliptic during twilight (this would be only during some seasons, depending on moon, sun, and avoid ecliptic in north) [access different NEO populations].

2: A series of NEO dedicated surveys - a 12 year survey, using deepest filters for NEOs (figure out what best SNR there is in each band for various weather/sky conditions) [increase NEO completeness, serve as a comparison point for "max NEO completeness possible"].
For all cadences, skip Milky Way, and relax airmass constraints to ~1.8. Also consider exposure time lengthening (to account for airmass and sky brightness increases away from zenith). Re-visit fields after 3-5 nights.

Cadence 1) - varying declination limits (+/-30 around Ecliptic, subject to airmass constraint -- probably only +10 above ecliptic in north) 1a) require same-night pairs, ~1 hour separation 1b) require triplets 1c) require quads, <2 hour separation

Cadence 2) - PS-style dec limits (+20 / -70 ) 2a) require same-night pairs 2b) require triplets 2c) require quads, <2 hour separation

Cadence 3) - Field of regard includes opposition-centered box, +/- 30 deg. height in Dec, +/- 20 deg. width, plus 10-degree wide ecliptic strip.
3a) require same-night pairs 3b) require triplets 3c) require quads, <2 hour separation

These alternative observing strategies sound very interesting! Is there any change that the results from some of them, specially the northern ecliptic in r band with WFD cadence, could be included in the whitepaper?

Hi Miguel, Lynne:

The plan is to include results in the white paper only based on OpSim outputs that we already have, but to also write in that paper about the OpSim runs we would like to see. New runs that we suggest (as Lynne is doing here) could be carried out by the summer, so that we would have some new strategies to test with our metrics then. I guess those results could then be folded into a version 2 of the white paper, in the fall perhaps.

That is a good plan. Thanks for the clarification. There are a couple of places in the paper that refer to the OpSim v3.2.1 results. I guess that these should be replaced by the newest v3.3.5 set of runs that are actually discussed?

drphilmarshall commented 8 years ago

If at all possible, yes! Also, to avoid confusion we should refer to OpSim runs by their name (eg enigma_1189) - there's a macro that enables easy cross referencing I believe. Only the initial description of ecah run need mention the version of the code that was used.

Hi @rhiannonlynne - can this issue be closed, or punted to the Tucson 2016 milestone? Thanks!

rhiannonlynne commented 8 years ago

Punt to Tucson 2016 milestone please.

drphilmarshall commented 8 years ago

Wheeee! :-)
