| 112 | === Dither test on DWFS9 in IFU 052 === |
| 113 | |
| 114 | Purpose: We want to see the reproducibility of the dithers imaged through the DWFS9 point grey camera which might be in IFU052. |
| 115 | |
| 116 | Procedure: |
| 117 | * Put a really bright star on IFU052 to confirm that we can actually confirm that it is right one (you will need a guide star to hold it steady. |
| 118 | * If you can confirm that this is the right IFU slot try the following steps |
| 119 | * Setup on a 14th mag star for IFU052 |
| 120 | * Guide on GC1 or GC2 |
| 121 | * make sure GROC < 400 |
| 122 | * make sure you are in dither position 1 |
| 123 | * take a few images with the point grey camera dwfs9 |
| 124 | * change to dither position 2 with {{{syscmd -P -v 'AdjustDither(pos=2)'}}} |
| 125 | * take a few images with the point grey camera dwfs9 |
| 126 | * change to dither position 3 with {{{syscmd -P -v 'AdjustDither(pos=3)'}}} |
| 127 | * take a few images with the point grey camera dwfs9 |
| 128 | * move back to dither position 1 and repeat the last 7 steps until you collect 3 cycles of data. |
