HWS Origin Crosses Updated on ITMs

Matt, Camilla

After TJ and Dave fixed the HWS Live GUI 87252, Matt and I checked on it and re-centered the origin crosses which are meant to mark the center of where the IFO beam is heating the ITM, before and after, sdf diff. We moved them both down but we hadn't updated them in a few years so this isn't too surprising. 

Also attached is a HWS image of the test masses comparing getting to 60W in to 180s later, plot. As usual, ITMY looks clean and ITMX has it's known point absorbers. There is some edge effects on ITMX that should be ignored.
