STARDUST NAVCAM RAW PREFLIGHT CALIBRATION IMAGES V2.0

This dataset contains the raw, preflight, thermal-vacuum calibration images collected by the Navigation Camera (NAVCAM) on 8-10 April 1998 for the Stardust mission. This is version 2.0 of the dataset, in which the original image data were converted from the standard PDS IMG format to the FITS format; no corrections were applied. The NExT mission to comet 9P/Tempel 1 used some of these preflight data to check the exposure time offsets due to shutter reversal and to determine dark current rates. This dataset supersedes version 1.0 which was safed by PDS because the data were not considered to be scientifically useful for the Stardust mission, due to problems encountered during the flight (stuck filter wheel, contamination on the instrument window, etc.) that changed the instrument characteristics.
