Friday Jan 23rd Sheila, Karmeng, & myself removed 3 Irises, and swapped out a PD for a beam dump.
First Karmeng & I Turnt up the purge air & took pictures of the table.  
Then we found all the irises Sheila wanted to remove:
Iris 1.... which was one of the 3 Sheila wanted to remove along with Iris 2 and Iris3 near by.

We decided to swap a Photodiode for a Beam Dump due to the scattered light documented in this here FRS ticket, as putting a beam dump infront of the PD was not possible due to Space constraints.
Swapping this PD out required some expert level HAM7 Yoga so Shelia did the switcheroo.

I'm sure it will be fine, but the PD was in place to catch light that is there when the IFO is locked.... and well since the IFO wasn't locked... we Eyeballed the placement of that beam dump that took it's place.  So we are fairly sure the Beam Dump is in the right place.  Oh! I took a few before pics of the PD too just to do some comparing with the after pics of the Beam Dump.
We did check all the beam paths in HAM 7, but that last beam dump we can't check so ¯\_(ツ)_/¯ Looked good to us.

Thanks to Jordan for the last minute purge air cram session.

Later!
