== 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.
