DATA_SET_DESCRIPTION
Data Set Overview : This data set consists of all the uncalibrated data collected by the Remote Micro-Imager (RMI) camera. The ChemCam remote micro-imager (RMI) provides high resolution images primarily to give the morphological context for the LIBS analysis points, though it can also be used for imaging other features on Mars. It consists of a 1024 x 1024 pixel camera with a field of view of ~20 mrad. Its resolution is approximately 100 micro-radians. The RMI images a broad spectral band by picking off about 10% of the light from the ChemCam telescope. Having a narrow depth of focus, it uses an autofocus algorithm to acquire targets with in ~20 m, and can be focused manually to infinity. Images can be compressed without loss or with a lossy algorithm, and can be downlinked as thumbnails or subframes.    Parameters : RMI Imaging: The imager software inherited from Rosetta includes autoexposure algorithms, with typically four different exposures made, and the best image is kept. For a typical rock analysis scenario a full 1024x1024 pixel image is taken prior to LIBS analysis, and an image of only the analysis spot (e.g., 128x128) is taken subsequent to analysis. While LIBS and RMI will be used frequently together, there will be numerous times when RMI will be used separately, such as to provide close-up images to support arm-mounted experiments, or provide images of very distant objects.    Processing : This data set uses the Committee On Data Management And Computation (CODMAC) data level numbering system. The EDRs are to be reconstructed from 'Level 1' or 'Raw Data', which are the telemetry packets within the project specific Standard Formatted Data Unit (SFDU) record.  CHEMCAM EDRs were generated by the MIPL (Multimission Image Processing Laboratory) at JPL under the Operation Products Generation Subsystem. The EDRs are raw uncalibrated data reconstructed from telemetry data products and formatted according to the Camera EDR/RDR Software Interface Specification. Meta-data acquired from the telemetry data headers and a meta-data database were used to propagate the PDS label.  RDRs will be produced in succession by the ChemCam Team and formatted according to this SIS, the RDR data product will be placed into FEI for distribution.   Data : The data are stored in multiple data files and have been organized by data products.  For RMI the data product consists of the following: Ancillary Data which includes sclk, tempertures and command parameteres and arguments. SOH Data Before and after the image. Auto Focus data if the Autofocus was used. Image Science Data As well as Command Reply data for each DPO.  An attached PDL Label describes the content of the data file and format of the data can be found in referenced .FMT files.  Ancillary Data : Most of the ancillary data needed can be found in the data it self or in the label portion of the EDR. Also included will be an Ancillary DPO.   Coordinate System : ?

For a typical rock analysis scenario a full 1024x1024 pixel image is taken prior to LIBS analysis, and an image of only the analysis spot (e.g., 128x128) is taken subsequent to analysis.
