Half-way progress report. In summary, after ditching the Jun 26th wall-spot as a reference, we've re-aligned the bypass beam to a slightly modified IMC alignment. We now see beams on the ISS QPD array, as well as the IM4 TRANS QPD, with good SUM values. We've moved the over all beam UP going into the PRC, as expected was needed (though still for an unknown reason). With this alignment, we have a beam centered on PR2 and PR3. We now move on to check the centering on the ITMs, and continue to output arm for OFI alignment check.

Blow-by-blow of this morning's activity:
- Set up temporary IMC TRANS camera, found IMC flashes weren't awesome
- Tweaked MC3 pitch/yaw to get good flashing (P = from -550 to -700 [urad], Y = from -2557 to -2550 [urad])
- Re-aligned bypass beam to IMC trans flashing
- Beam looks good on 2014-06-26 wall spot, but 
    - too low on IM4 TRANS QPD, 
    - doesn't show up on ISS array
    - still too low on PR2 with IM4 P alignment close to its limit
  similar to where things were left yesterday.
- Decided to give up on 2014-06-26 wall spot since its the only figure of merit "correct," 
- Also guess that its not MC3 that's causing bad flashing, but MC1
- Added copy of LP filter from IM4 TRANS QPD SUM to ISS QPD SUM filter bank to better track amount of light on ISS QPD
- Restored MC3 alignment
- Tweaked MC1 alignment to get good flashing on temp. (P = from 1254 to 1100 ; Y = from -2366 to -2400)
- Re-aligned bypass path to IMC TRANS path, found beams on both arriving IM4 TRANS QPD and ISS QPD. Spot now high ~7 [mm] from 2014-06-26 wall spot.
- Walked beam up between IM2 and IM3 (subtracting pitch in IM2, adding pitch to IM3), beam still looks OK going through the IFI 
     (New alignments IM2 and IM3 P = +18000 and +18000; Y = 5154.7 and -2500)
- Now beam is centered on IM4 TRANS QPD and ISS QPD, and shows ~ 30 [ct] and ~ -370 [ct] on their sums, respectively.
- Wall spot is now ~7 [mm] high, but beam is centered on PR2.
- Block MC1 and MC3 with metal shields to prevent IMC flashing 
- Increase laser power to 1 [w], sum on IM4 TRANS QPD and ISS QPD is 100 [ct] and -2000 [ct].
- Draw new spot on wall, marked ast 2014/Jul/16, 7 [mm] above previous spot.
- Checked centering on PR3, looks OK. Break for lunch.


Given that with wall-spot is the only figure of merit out, we deem this new alignment of the mode cleaner and subsequent.  Good!
