INTRODUCTION
======================================================================

  This archive contains the science data acquired by the VMC camera
  onboard the Mars Express mission.

  The VMC camera was originally intended as an engineering camera to
  monitor the release of the Beagle-2 lander, but has subsequently
  been used for outreach and scientific purposes. In 2016 it was
  designated a science instrument.

  VMC takes images in a stream of 8 bits. For more information on the
  VMC, please refer to the catalog INSTRUMENT.CAT and EAICD document.

DATA SET INFORMATION
======================================================================

The Level 3 PNGs are BROWSE products and should not be used for
anything relating to photometry. The correction of the vignetting
effect is undone for these BROWSE images so that the values can be
stored in 8 bits (which does not allow for values above 255). These
PNGs are colour-enhanced and include a sharpening filter to enhance
the contrast, as well as a median filter to reduce noise. These
filters may produce artefacts in some cases, and therefore these
products are not intended for science (instead, the RAW and FITS
products should be used).

The structure of the dataset is as follows:
