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.
