Chris, Kiwamu, Sheila,

I just transitioned the PS to science mode, in the hopes that this will at least simplify troubleshooting the aligment problems we are having if we dont have the 20 minute temperature swings anymore. 

Chris has written verry nice scripts that take snapshots of the two transmitted cameras, and calculates the centroid. 

The ref cav trans centroid is temporarily plotted as H1:LSC-DARM_OFFSET and H1:LSC-MICH_OFFSET and the PMC trans centroid is saved as H1:LSC-SCRL_OFFSET and H1:LSC-PRCL_OFFSET. 

we can use this decide if the cavities themselves are moving.
