The config3 transition yesterday went:

Wiki Markup1. Move the east horiz array up 3 slots.     (This measured at \ ~4.87m for the top of 5b's boom to the base plate.) \ [started \ ~0600\]

2. Move the west horiz array up 3 slots.

3. Move 6t and 6b up.

4. Move 12b up.unmigrated-wiki-markup

5. Move 5.5m and 4.3m up to \ ~5.8m and \ ~4.8m (also T/RHs) \ [done by 0830\]unmigrated-wiki-markup

6. Tear-down upwind and move to staggered upwind, sequence 11u \ -> 3u \ [done by 1230\]

Wiki Markup7. Remove upwind bases \ [1530-1630\]  

When we started to build config 3, we measured 3.254m from the config 3 reference line  to the top of 5b's boom (of course, after raising it to its position).  New measurements for other sensors:

...

All of the upwind sensors were set to 3.261 = 3.254+0.7 to the top of the clamp +/-1mm.

P.S. The reference height mark #3 is 15.2cm below the mark for #2. 

P.P.S. Some spacings:

5t  133.4cm  6t  127.4cm  7t

5b 133.7cm  6b  127.8cm  7b

11b 128.3cm  12b  132.0cm  13b
