  Data Set Overview
  =================
  
    Version 2.0 of the Pancam IOF Reduced Data Record was generated using new
    calibration data and proceduers. Details of the new calibration are found
    in the file PANCAM_IOF_V2_SUMMARY.TXT in the DOCUMENT directory.
    
    The remainder of this text is carried over from the Version 1.0 data set
    description.
    
    This data set contains Pancam reflectance products known as
    'IOF' files. IOF is defined as the ratio of the bidirectional
    reflectance of a surface to that of a normally illuminated
    perfectly diffuse surface. This ratio is also known as the 'radiance 
    factor'. IOF is equal to I/(pi*F) where I is equal to the measured
    scene radiance, and pi*F is the solar irradiance at the top of the
    Martian atmosphere for a given Pancam bandpass. IOF products are 
    useful in that they place the Pancam data in the same context as 
    laboratory or telescopic reflectance measurements or radiance 
    factor data from other Mars orbiter or landed missions. See
    BELLETAL2006 for the assumptions and methods used in generating 
    the Pancam IOF products contained in this data set.

    IOF products have attached PDS and VICAR labels, along 
    with the binary image data. 
    
    IOF image data are stored as scaled 2-byte integer values rather
    than real IOF floating point values. Conversion of the integer
    values stored in the data products to real floating point values
    requires the use of the values of the RADIANCE_OFFSET and 
    RADIANCE_SCALING_FACTOR keywords in the PDS label. The real
    floating point values of IOF can be computed using the equation
    
      IOF = RADO + RADSF * IntVal
    
    where IOF is the true IOF value, RADO is the value of the 
    RADIANCE_OFFSET keyword, RADSF is the value of the 
    RADIANCE_SCALING_FACTOR, and IntVal is the integer value
    stored in the image file.


  Processing
  ==========
    MER Pancam IOFs are considered Level 3 (Calibrated Data
    equivalent to NASA Level 1-A). IOF image products are 
    generated by the Athena Pancam Science Team from the 
    Science radiometrically calibrated products 
    (PDS data set: MER1-M-PANCAM-3-RADCAL-RDR-V1.0) using
    the methods described in BELLETAL2006.
