*: sonic height changed from previous configuration
#: changed sonic since previous azimuth measurement
cal: azimuth entry in calibration file = measured magnetic azimuth - 131.7
For configuration 3, the 3b azimuths are more consistent with previous and
following azimuths than are 3a. I (twh) used 3b for the profile cal_files.
Both Semmer and Oncley measured azimuths for the horizontal arrays in configuration
2, and Militzer and Oncley measured azimuths for the horizontal arrays in
configuration 3. In both cases, Oncley's azimuth measurements were ~4 degrees
larger than the others. Thus we will use Semmer's azimuths for configuration2
and militzer's for configuration 3 . Also oncley recommends using the 'surveyed'
horizontal array azimuths for configuration 4, which in this case are mostly very close to Oncley's measurements.
