Data Set Overview
  =================
    A Disparity file contains 2 bands of 32-bit floating point numbers
    in the Band Sequential order (line, sample). Alternatively, line and
    sample may be stored in separate single-band files. The parallax, or
    difference measured in pixels, between an object location in two
    individual images (typically the left and right images of a stereo
    pair) is also called the disparity. Disparity files contain these
    disparity values in both the line and sample dimension for each
    pixel in the reference image. This reference image is traditionally
    the left image of a stereo pair, but could be the right image for
    special products. The geometry of the Disparity image is the same as
    the geometry of the reference image. This means that for any pixel
    in the reference image the disparity of the viewed point can be
    obtained from the same pixel location in the Disparity image.

    The values in a Disparity image are the 1-based coordinates of the
    corresponding point in the nonreference image. Thus, the coordinates
    in the reference image are the same as the coordinates in the
    Disparity image, and the matching coordinates in the stereo partner
    image are the values is the Disparity image. Disparity values of 0.0
    indicate no valid disparity exists, for example due to lack of
    overlap or correlation failure. This value is reflected in the
    MISSING_CONSTANT keyword.


  Processing
  ==========
    This Operations RDR is produced by OPGS/MIPL using the Mars Suite of
    VICAR image processing software.


  Data
  ====
    2 bands, Float, DualPDS/VICAR (OPGS) binary file.


  Software
  ========
    The MIPL Mars Program Suite was used to generate these RDRs.


  Media/Format
  ============
    The data set will initially be delivered and kept online.  Upon
    Mission completion, the Panoromic Camera Operations RDRs will be
    delivered to PDS on DVD.
