| 56 | | === Run full tracks with bib camera+ to assess WFS corrections === |
| 57 | | |
| 58 | | * Use do_shuffle to setup on a V=12 star near start of track == twilights tests == |
| 59 | | |
| 60 | | === VIRUS special twilights === |
| 61 | | |
| 62 | | Purpose: There is some interest in seeing what the long term illumination correction changes look like including what different track positions do to them. The script is "specialtwilight" in /home/mcs/astronomer/bin/. It takes a single argument which is the Observation number. |
| 63 | | |
| 64 | | Procedure: |
| 65 | | * Setup the guide camera for sky twilight (GC2, 0.1 sec exposure, B filter) |
| 66 | | * When you hit the correct flux level (biased to a slight higher value, perhaps 5k) execute the specialtwilight script |
| 67 | | |
| 68 | | |
| 69 | | |
| 70 | | * '''See that previous two plans for notes on how we modified the flane.txt file for this.''' |
| 71 | | * Have TO focus up and have RA center at least one OWFS |
| 72 | | * Use GUI in PAS to move star to bib and hold probes on their targets |
| 73 | | * close focus loop |
| 74 | | * set bib exposure to 2sec (for V=12 star) |
| 75 | | * Record a time in On-skythe log |
| 76 | | * Use TO save images button to save gc1,gc2.wf1,wf2,bib images |
| 77 | | * It is good to chek that "Store Images" button is now clicked in all camera gu |
| 78 | | * '''In this test we should apply X,Y offset corrections as they become necessary''' |
| 79 | | * If TO makes a Tip-Tilt change record the time in the log |
| 80 | | * If TO makes a GRoC correction record the time in the log |
| 81 | | * Run until the end of track |
| 82 | | * when done, record a time in the log |
