Data Set Overview
  =================
    This data set consists of images of the geologic context of each
    target sampled with the ChemCam Laser-Induced Breakdown Spectro-
    meters (LIBS). The Remote Micro-Imager (RMI) image field-of-view
    of about 20 mrad for 1024 pixels is adequate to localize the laser
    pits by comparing the image taken before and after the laser
    activities. The depth-of-field varies from 4 to 1000 mm as function
    of the target distance (respectively between 1 and 20 m).
    Most of the time the exposure time is set by an autoexposure
    algorithm; It is generally around 20 msec.
    
  Parameters
  ==========
    The RMI camera head made of a Thomson-CSF TH7888A detector 
    (1024 x 1024 pixels, 10 bits) and produces monochromatic images.
    The photometric response is very close to linear up to 670 DN
    (with a gain setting of 13), while the saturation level is at
    840 DN.
  
  Processing
  ==========
    The RDRs have been processed to remove dark current, smearing and
    flat field effects, as well as ghost images from the raw EDRs. 
    The image is also streched before being saved as TIF file. 
    This produces Partially Radiometrically Corrected (PRC) images.

    These images are generated by JPL's Multimission Image Processing 
    Laboratory (MIPL) under the OPGS subsystem, using a code developed
    by Olivier Gasnault at Institut de Recherche en Astrophysique et
    Planetologie (IRAP).

  Data
  ====
    Each RMI RDR, also known as Partially Radiometrically Corrected (PRC),
    is made of a pair of file: a standard TIF file and a detached label
    text files (LBL).


  Ancillary Data
  ==============
     The ancillary data in the RDR detached label file are the same than
     those in the EDR file that was used as input.
  
  Coordinate System
  =================
     The coordinates available in the RDR detached label file are the
     same than those in the EDR file that was used as input.

Confidence Level Overview
  =========================
     The RMI RDR images are not fully corrected radiometrically and
     are only meant to be used for qualitative interpretation of the
     context at small scales.
  
  Review
  ======
      This ChemCam archive has undergone a standard Planetary Data System
      peer review.
  
  Data Coverage and Quality
  =========================
      Similar to ChemCam LIBS coverage.
  
  Limitations
  ===========
      See confidence note above.
