In order to test the alignment of HWS Y-arm beam and the spherical power measured, we need to run a test by using the ring heater (RH) of ITMY. tonight after commissioning.  Here are the steps

1.  Leave all optics aligned. The most important optics need to be aligned are ITMY, BS, and SR3.

2. Run the the python script to turn on the RH to 1 W. This script turns on the RH if ITMY and leaves the RH on for 2 hours before turning it off.

 To run the script, type python ringheaterITMY.py to the terminal, which should have been readily available on the desktop. 

NOTE:

The script and all terminal windows should be readily seen on desktop opsws6. Attached is the screen of what the desktop should look like:

        There are two terminals:

            1. Terminal where the script is executed, it is in the folder ~/HWSYAlignment. the command python ringheaterITMY.py should be already typed onto the terminal and just need to prss enter to execute the script.

           2. One other terminal shows the HWS is running. DON'T close this terminal, otherwise the HWS will stop running

         There is also a window showing the script ringheaterITMY.py
