Self Stacking
It is important during self stacking that the HET shutter and CCAS tower remain closed. Do NOT open these shutters during this procedure. This is the procedure used for checking the operation and functionality of the wavescope along with the AOA software.
There are two ways that self stacking can be done; Automated and Manual.
Method 1: Automated
This method will automatically move the reference shutters but stop before doing an unnecessary DMI measurement and corrections.
1.) In the APC control window make sure to turn on the wavescope.
2.) Also check to make sure MARS is started and running.
3.) On the camera control, go to channel 2 to view AOA.
4.) In the windows machine, start the wavescope software and select manual alignment. In the pop up select the last file.
5.) Type 's2' into the wavescope software terminal.
6.) When you are done checking the AOA and Wavescope, make sure to close the reference shutter and to turn off the wavescope in the APC GUI.
Method 2: Manual
This method will go through the entirety of the initial stacking iteration (s0 or first s1 of the night) including a DMI measurement and making tip/tilt corrections. These measurements are extremely small and virtually useless during self stacking so it shouldn't adversely affect anything.
1.) In the APC control window make sure to turn on the wavescope.
2.) Also check to make sure MARS is started and running.
3.) On the camera control, go to channel 2 to view AOA.
4.) In the windows machine, start the wavescope software and select manual alignment. In the pop up select the last file.
5.) In the wavescope software terminal enter the command shuttermode then do an S0 command.
NOTE: The wave scope software will then begin to send a series of prompts. It will ask for you to open HET shutters during this time, do NOT open the HET shutter. Rather treat every command as if it were a command for the reference shutter (bear in mind this will result in some duplicate commands, if two open commands occur in a row just keep the reference shutter open and click ok on the prompt).
6.) Follow the prompts as if they are for the reference shutter and make sure to click ok for the script to continue.
9.) When you are done checking the AOA and Wavescope, make sure to close the reference shutter and to turn off the wavescope in the APC GUI.
