Level 2 Help for TOTOPO

There are Four input files.
File#1: This is the left or first input image given to
        program TRACKER.
File#2: This is the right or second input image given to
        program TRACKER.
File#3: This is the MARK file written by program TRACKER.
        It is 'REAL' format with 512 byte records containing
        pairs of tiepoints in the order:
        left_line,left_samp,right_line,right_samp.
File#4: This is the output of program LSTOXYZ containing either:
        X,Y,Z,ERROR or Lat,Lon,Range-radius,Error

The same size as the first input but contains either:
1. The topomap
2. The left input orthonormal view.
3. The right input orthonormal view.
REAL format.

This dictates the nature of the output file. Three outputs are
possible. These are:
MODE=TOPO  Which writes out an elevation map.
MODE=ORTHL Which writes an orthonormal version of the first (left)
           input.
MODE=ORTHR Which writes an orthonormal version of the second (right)
           input.
MODE=ERROR Which writes the miss distance between the two vectors
           solution for XYZ.
Default is TOPO.

Prints the line,sample and lat,long for each point in the input
Mark file as it is processed.

Specifies that the Fourth input file will contain the (X,Y,Z,error)
values in planet coordinates rather than the
 (lat,long,range-radius,error) values which are the default.

If no data is assigned to any pixel in the output file
(because of a sparse tiepoint grid) the un-assigned
pixels will be set to NODATA. Default is 0.0

Radius of circle within which points are collected to be used to
interpolate over the central pixel (if it is zero).
RADIUS should be greater than the grid size used in tracker3.

For interpolation to be performed a minimum of MINPTS must be
collected within the circle.

Number of passes to be performed through the image. If no points
are interpolated then iteration ceases.
