Same beamformer from Jan 12 (100112_log.txt)
Beam designed to point at meridian, zenith angle 22 degrees (theta=22deg, phi=-90deg)
  Optimized for 38 MHz
  Should be good for CGP observation

-- Jan 13 ------------------------------------------------------------

k1: s60 channel 10 ("A") (35.00-38.50 MHz)
k2: s60 channel 9        (31.50-35.00 MHz)

Just before overnight run:                     k1 is running 71 seconds ahead of k2.
Just after overnight runs (0430 local Jan 13): k1 is running 76 seconds ahead of k2.

Overnight run:
using lwa_700k.sh (see 100111_log.txt for details)
Crab pulsar transits about 22:19 local, directly through beam center 
==> started run 21:00 local, should run until about 00:52 local 
==> folder: 100113_k1, 100113_k2

Site visit by Greg Taylor.

He changed tuning of k2's s60 such that we now have:
k1: s60 channel 10 ("A") (35.00-38.50 MHz)
k2: s60 channel 14 ("E") (49.00-52.50 MHz)

He added USB hard drives to k1 and k2.  Couldn't mount them, so no data offloaded.  No new data taken since k1 & k2 drives were still loaded up with previous two nights data.

He added 1TB hard drives to k1 and k2, in addition to the ones Greg installed yesterday.  After considerable fiddling including multiple reboots of k1 and k2, all drives are ext3 and seem to be working OK.  No new data taken; instead spent the night transferring data from Jan 12 and Jan 13 overnight runs to Greg's drives.
