Missing mirrors in the reference measurement of AOA

The ultimate goal here is for the mirror locations for each mirror to be in a file called mirror_locations.txt on the wave computer in the location C:\aoa\mirror_locations.txt.

Step 1: Obtain a spot image of the reference grid.

• under the wavescope software go to the menu selection Alignment->Manual, select the "Show Spot Image" under the Reference Source.
• snap an image using the command "snap <filename>" (this will save the image in E:<filename>.fits)

Step 3: Check spot locations

• ds9 /home/mars/guider/wave/<filename>.fits
• see if the spot locations are close to existing mirror_locations.txt.
• you can quickly determine the xy coordinate of largest pixel value at the location you're looking by going to Regions > Shape > Projection and then clicking and dragging the cursor over the spot. This show a plot of those pixel counts and their xy coordinates.
• adjust the mirror locations file with the coordinates from the plot for the associated mirror.
• you may want to copy over the mirror_locations.txt to E as well to make this go faster.

Step 4: Create new spot locations if needed

• (iraf stuff)

Step 5: Copy the new mirror_locations.txt to the AOA software directory

• place a copy of the new file in /home/mars/guider/wave/mirror_locations.txt and /home/mars/guider/wave/mirror_locations_YYYYMMDDCDD.txt e.g. mirror_locations_20181222C13.txt where the last digits are for the temperature.
• go to the wave computer, open up the shortcut to aoa
• rename the current mirror_locations.txt to mirror_locations.txt-old
• navigate to the E: drive, copy the two new files to the aoa directory

Step 6: restart the wavescope software if needed.
