Test Plan

(1st version by JS, 12-Jan-2012)

1. with the extension dewar, we see no other possibility than to mount gismo at its new position in the receiver cabin, attach the new extension dewar, and then pump on it in the receiver cabin.
2. test plan: as you will see, we anticipate that we will need almost 60 hours to really characterize the instrument sufficiently (w/o overheads, only a few of the following points really seem debatable if we want to guarantee GISMO's readiness for April):
3. alignment: optical, 2 hours
4. alignment: radio 3 hrs
5. verify neutral density filter needs 1 hr
6. spillover characterization 2 hrs

7. initial x-y-z focus & beam map 1hr

8. verify and debug astrometrical parameter exchange with 30m control system by using different offsets, etc. (dending on needed debugging needs) 1-5 hrs
9. beam map in order to determine the pixel position and plate scale 2 hrs

10. complete focus model (at different elevations) each elev 1 hour -> 5-7 hrs total

11. beam maps at different elevations 1 hr per elevation: 5-6 hrs
12. pointing model 5 hours
13. demonstrate noise integration with smallest Lissajous pattern down to confusion limit (we assume NEFD 10mJy s^0.5, confusion limit: 50 microJy): 11 hrs.
14. primary calibration (counts vs flux) on major calibrators (planets) 3hrs.
15. primary calibration factor for different neutral density settings: 2 hrs.
16. measure secondary calibrators vs primary calibrators (galactic sources, incl. compact HII regions, major solar system moons (in order to calibrate their temperature) .25 hrs/calibtators, total 2-3 hrs.
17. empirical verification of sensitivity vs scan patterns for future time estimator. per scan pattern 0.5 hrs per scan pattern, total 6 hrs total.
