At about 10:00 local, k1 is currently running 55 seconds ahead of k2.

Same beamformer from yesterday, but repointed
Beam designed to point at meridian, zenith angle 22 degrees (theta=22deg, phi=-90deg)
  Optimized for 38 MHz
  Should be good for CGP observation
Stand 187: ARX channel inop,            Delay=38.5 ns ** not used **
Stand 189: BalunBoard=1, Transformer=4, Delay=26.0 ns
Stand 191: BalunBoard=4, Transformer=1, Delay= 3.0 ns
Stand 210: BalunBoard=3, Transformer=3, Delay=11.0 ns
Stand 212: BalunBoard=4, Transformer=3, Delay=27.5 ns
Stand 214: BalunBoard=2, Transformer=3, Delay=12.5 ns
Stand 228: BalunBoard=4, Transformer=4, Delay= 2.5 ns
Stand 230: BalunBoard=2, Transformer=4, Delay= 0.0 ns

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

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: 100112a_k1, 100112a_k2

Just after overnight run (0430 local Jan 13): k1 is running 61 seconds ahead of k2.
