Subject: Relocate green TRX and TRY components from PSL table to BS table 

[JC, Tega]

Tega and I cleaned up the BS OPLEV Table and took out a couple of mirrors and an extra PD. The PD which was removed is "IP-POS - X/Y  Reversed". In addition to this, the cable is zip-tied to the others located on the outside of the table in case this is required later on. 

Next, we placed the cameras and mirrors for the green beam into their postions. A beam splitter and 4 mirrors were relocated from PSL table and placed onto the BS Oplev table to complete this. I will upload the picture of the newly updated photo with arrows of the beam routes.
