NGIMS












                                                 Requesting Specific NGIMS Data



    Data Type
    The data products are simple ASCII tables. The NGIMS data consists of 5 components: Raw, Calibrated and Derived Single Species Abundances and Altitude resampled abundances. Each file spans one MAVEN orbit, covering the interval when the craft was at an altitude of 500Km or less.

    Indices, that can be used for planning data selection, tabulate information associated with each periapsis passage for which NGIMS data is available. The associated geometry is given at the time of periapsis passage.
