Confidence Level Overview
    =========================

      All telemetry data frames produced by MIDAS contained checksums
      that were validated upon ground receipt.

      During the processing of the data in preparation for delivery
      with this volume, the structure of the telemetry data packets
      was verified. This verification included detection of both the
      DDS header and the length of each packet, which ensured that all
      packets were complete and not damaged.

      The validity of the data has been approved by the MIDAS Science
      Lead and Science team members by review of the included images
      and evaluation of the associated housekeeping information.

      The dataset has passed the Comet Science Data review held in
      October 2018.

ABSTRACT_TEXT The Micro-Imaging Dust Analysis System (MIDAS) is an instrument on the ROSETTA Orbiter that will provide 3D images and statistical parameters of pristine cometary particles, collected in the vicinity of comet 67P/Churyumov-Gerasimenko. This data set includes reference measurement data acquired with the flight spare unit (FS) on ground, which was used for improving the accuracy of the images gathered by the actual flight unit and to develop adequate measuement procedures for flight. The test data was collected during several years and spawns several data sets, in order to keep the individual data set size on a reasonable level. The current dataset contains data from 2008.
