| | 40 | === Focus test: GC1-GC2-DWFS8 === |
| | 41 | |
| | 42 | Purpose: We want to measure the focus of GC1,GC2 realtive to DWFS8. |
| | 43 | |
| | 44 | Procedure: |
| | 45 | * Set up on a foc09 star in the usual way (i.e. yse do_shuffle or gstar to put the V=9 star in DWFS8 and guide stars in gc1,gc2). |
| | 46 | * Have TO set-up and guide on either gc1 or gc2 |
| | 47 | * Have TO use DWFS8 to focus the star |
| | 48 | * Record GroC |
| | 49 | * Use /home/mcs/astronomer/script (modified by SIR on 20161107) to collect GC1, GC2 images at different focus settings. |
| | 50 | * Record GRoC |
| | 51 | |
| | 52 | The above sequence would comprise one data set.As of 20161107 HL is requesting that we collect 20 sets to complete this test. |
