Now guidedog logs the centroid values while guiding.
There is a sample from last night:

   log.txt is the centroid data begin logged by guidedog from Feb 5th.
   example line: 04:36 TCS_Offset to tcs3_host  -0.5 0.9 Pt.Peak.Inc -0.42 -0.46
      The 1st pair of values, '-0.5 0.9' are the raw correction from the image.
      The 2nd pair of values, '-0.42 -0.46' are after guidedog applies rotation and gain.

   Files I created from log.txt.
      peak.txt  is just the corrects being sent to tcs3
      small.txt is are centroid value too small to be transmitted to tcs3.
      hr.txt is data from 3:00 to 4:00.


Now to the graphs....

   1.pdf - show the the centroid values after rotation and gain.
           The red is from small.txt - values too small to be corrected by tcs.
           The green is from peak.txt - correction sent to tcs.

   Note that from 1:30 to 3:15, very little correction sent to tcs3 (tracking is good).

   hr.pdf just zoom in on 3:00 to 4:00 (both small and peak are graph together).

   I also plotted the -0.1 and +0.1 values show when correction are big
   enough to be send to the tcs.
