Help for TGEOM2

PURPOSE
      TGEOM2 is the third and final program in the triangular geometric
rectification sequence, following TRIGRID and TGEOM1.  TGEOM2 accepts as input
the rectification dataset that was output by TGEOM1 and the raw image to be
rectified.  It produces as output the geometrically rectified image of the
second input.  The user may choose between bilinear and nearest neighbor
interpolation methods.

RESTRICTIONS:          
      TGEOM2 reads the entire raw image into memory.  This can result in
swapping and similar efficiency problems for large input images.  The point
at which this becomes a problem depends upon the size of the input image, 
the amount of memory on the machine, and the loading of the machine by other
jobs.
