19:20 opening the Right Shutter Door...

19:20 Marco is updating the DX collimation table with the one computed from data taken on 29 December. The SX collimation table was updated already.

19:40 Z11=1000 nm to SX. SX has all GO = 0.

19:43 Z7 = +2000 to SX.

19:43 Right Shutter Door cannot be opened.

19:50 Z4 = -1200nm SX

~20 red shutter door opened.

Collimation data for SX - 4 points obtained:

# mirrorX mirrorY mirrorZ+0.8mm mirrorRX mirrorRY elev LBTtemp # x y z rx ry imagenumber

22:20 Collimation data for DX started. GO are 0.2 0 0 0 0 0

between 22:20 and 00:20 collected data for model - 8 points from 37 to 84 degrees elevation.

00:20 loaded new SX and DX collimation lookup tables. With these, all Global Offsets are zero.

02:00 co-pointing at 85 deg elevation yields a set of pointing offsets for SX - Wayne is applying these (02:52) to the SX global offsets, which are now X Y Z RX RY RZ = -0.116mm 0.205mm 0.0mm 4.4" 2.5" 0.0".

02:50 I edited two files to include the new F972N20 filter: 1/ "redfilterslist.dat" on the CMU to replace pinhole with this... BUT we have a real concern about whether 2/ fwr.conf file in /home/lbcobs/OBGUI/conf to include the F972N20 list.
