Globular cluster NGC5272 dithering test

Purpose: There are two different reasons for this test 1) Look for orientation issues of the IFUs 2) Determine the difference that dithering and the guider orientation have upon each other, including probe position.

Testing of the ACAM position

Purpose: We want to see if the ACAM position changes with respect to the IHMP over time. We want this data every night and when ever we get an unusually high or low temperature. It would be good to vary the Az as well.

Determine the Center of the BIB:

• Select a 14th mag star in a reasonably rich field with shuffle for the BIB
• Setup on the very center of the BIB field of view and save an image note any differences from the wiki center position.
• Guide on one of the guide probes
• Put in the ACAM and save an shallow image with the target star not saturated.
• Report on the position of the BIB in the night report and on NightOperations/Commissioning/Results
• Save a deeper image which should show more than a dozen stars.

Determine the Center of LRS2-B

• Select a 14th mag star in a reasonably rich field with shuffle for the LRS2-B
• Setup on LRS2-B and start guiding on one of the guiders
• Take LRS2-B spectrum, probably 60 seconds.
• Adjust the position so that the star is at the center of LRS2-B IFU using lmap until the offsets are less than 0.3"

syscmd -T 'Guider1_offset_fiducial ( dx_asec=-0.01,dy_asec=0.55,compensate="false")'

• Confirm the star is at the center of the IFU by taking a spectrum.
• Once it is as the center of the IFU put in the ACAM and take a shallow image so that the star is not saturated.
• Report on the position of the LRS2-B in the night report and on NightOperations/Commissioning/Results
• Take a deeper image so that there are large number of stars.

Determine the Center of LRS2-R

• Select a 14th mag=== Testing of the ACAM position === star in a reasonably rich field with shuffle for the LRS2-R
• Setup on LRS2-R and start guiding on one of the guiders
• Take LRS2-R spectrum, probably 60 seconds.
• Adjust the position so that the star is at the center of LRS2-R IFU using lmap until the offsets are less than 0.3"
• Confirm the star is at the center of the IFU by taking a spectrum.
• Once it is as the center of the IFU put in the ACAM and take a shallow image so that the star is not saturated.
• Report on the position of the LRS2-R in the night report and on NightOperations/Commissioning/Results
• Take a deeper image so that there are large number of stars.
