= Summary STS.refstack.20120510 = 
[[PageOutline]]

MOPS would like a refstack for the STS fields to do warp-stack diffims.

The previous STS.refstack.20110613,20110615 wasn't usable as it was destroyed by magic.

STS.20120510 was made using a similar number of inputs from the best exposures from 2011. Not pretty but hopefully sufficient.

Status:
 * 5/ : test samples for refstack finished
 * 5/ : refstack finished
 * 5/ : test sample 1
 * 5/ : test sample 2 

Details to add:
 * FWHM of test stacks (STS.reftest.20120510.c#f#) like done with MD refstacks
 * unconv vs convolved stacks and issues found
 * test diffims with recent STS data



= STS observation and tessellation summary =

rawExp.comment name details 

 * GIQ -- shorter exp_time (20s) to not saturate more sources in better seeing conditions
 * ND -- no dither so always with center and typically with 30s, occasional NDGIQ
 *  NOM -- nominal IQ?
 * 000,090,180,270 -- rotator to keep rough PA on field over season
 * PP# -- 1-7, 7 pointings
 * dither 1-4 - dither shifts (by ?) and typically with GIQ



|| [[Image(STS_i_smf_fieldcolor.png,300px)]] || 7 projections and their skycell overlap (STS.V4, 0.25"/pixel platescale). ||

Approximate pattern, E left, N up:
{{{
 1 2

}}}


There is significant overlap of projections and skycells, may cause issue with general input into a refstack skycell with wildly different IQ.

= Test Diffim samples = 
Want to create a sample of diffims with detections for MOPS to look at. Will need to also keep in "full" state so they can get postage stamps quickly. Focus on projection 1.
