Apollo 15 Metric Instrument Kernel
========================================================================

   This Apollo 15 SPICE instrument kernel (I-kernel)
   contains the instrument geometric parameters for the Metric camera


Version and Date
--------------------------------------------------------
 
   Version 3.0 -- February 23, 2013 - Ken Edmundson 
      Negated INS-915240_TRANSX and INS-915240_ITRANSS
      so image coordinate system matches camera calibration 
      report. As one looks at scanned positives on the
      monitor, positive x is to the left and positive y is
      down.

   Version 2.0 -- March 16, 2010 - Ken Edmundson 
      Updated the focal length in comments to match actual
      value of 75.054. Corrected Reference #1 to 
      "ap15_sim_index.pdf" (previously referred to Apollo
      17). Added specific reference to original camera
      calibration report.

   Version 1.0 -- November 15, 2006 - Jacob Danton
