Summary STS.refstack.20120510

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

7 projections and their skycell overlap (STS.V4, 0.25"/pixel platescale).

Approximate pattern, E left, N up:

 1 2     
3 4 5   
 6 7

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.
