     9Notes:
     10 * During the period 130-166, the plane was equipped only with atmospheric measurement instruments for the SOLAS dust cruises.  As a result, there are no boresight numbers.
     11 * The 061-130 period was based on flight day 103a, using vector overlays to supplement the lack of cross-overs.  This was done because both calibration flights (061 and 130) had severe processing problems.
     12 * The 166 -> end of year period was based on the 166 calibration flight.
     13 * All Eagle and Hawk numbers may have small errors due to timing problems on every flightline.  The slippage caused by these errors may result in inaccurate placement of the markers used for boresight calibration.

     15No 2007 survey of the instrument positioning was done?  David Davis said to use the 2006 numbers as the placement of the Applanix IMU and instruments was identical (seems unlikely?).
     16 * ATM: 0.2655 0.006353 1.741
     17 * CASI: 0.4732 0.007934 1.702

     19 * Hawk: 0.6977 0.00781 1.994 (same as Eagle!)
