Describe Error_evaluation here.



Here are a list of error evaluation tools and ideas
 * formal uncertainty -- standard, bottom of the RESIDUALS.TXT.  Contains the fit of all the landmarks and overlaps.
 * Best 80% of landmarks.  Taken from ?
 * CompareOBJ
 * CompareOBJ TR
 * CompareOBJ --save-plate-error error
 * diffShape and gnuplot delta.gpi
 * SIGMAS.TXT plotted with sig.gpi
 * 2D heat map plot of number of images in landmarks
 * 2D heat map plot of residual errors for landmark
 * 2D heat map plot of residual errors for images
 * Evaluation of delta between truth S/C position and solved for S/C position:  as an RMS
 * 2D plot of delta between truth S/C position and solved for S/C position.
 * Number of "issues" (or >>) in MAPINFO, PICINFO and RESIDUALS.TXT
 


== To Do ==
 * Rebuild shape 3.7
 * Get RMS for each ZMAP
 * Run PreSurvey CompareOBJ

     . The 1st column is a list of 1. IMAGEFILES included in the landmark 2. overlaps with other landmarks 3. Limbs
     . The 2nd column is the error in deltaX (# pixels in image resolution)
     . The 3rd column is the error in deltaY (# pixels in image resolution)
     . The 4th column is the magnitude of the error (combines deltaX and deltaY)
     . The 5th column is the error in physical units (km)
