The following table shows wind component offsets as okay if the u and v offsets are less than +/- 4 cm/s and the w offsets less than +/- 2 cm/s.  If the zero wind offset exceeds these thresholds, the table lists the temperature range of the over-limit offset and the largest amplitude of the offset.  The plots of offsets versus temperature can then be examined to determine the exact nature of the offset.

The last 8th column relates to the following project, METCRAX, in October 2013.  The operating temperature range for night-time warm-air intrusions into the crater is on the order of -10 to +20 C.  The last column notes whether or not the sonic is suitable for that temperature range. 

10/4/13, twh:  Added columns 9-13 for post-project EOL zero-wind tests
