Villafranca del Castillo, 28692, Villanueva de la Canada, Madrid, Spain ====================================================================== INTRODUCTION ====================================================================== This archive contains the science data acquired by the VMC camera onboard the Mars Express mission during mission phase EXTENSION 3. 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. ====================================================================== DATA SET INFORMATION ====================================================================== root | |- AAREADME.TXT |- VOLDESC.CAT | |- CATALOG | | | |- CATINFO.TXT PDS catalog files for | |- MISSION.CAT mission, host, instrument, | |- INSTHOST.CAT references | |- INSTRUMENT.CAT | |- REF.CAT | ... | |- DOCUMENT | | | |- DOCINFO.TXT Overview of directory | |- EAICD_VMC.DOC | |- EAICD_VMC.PDF | |- EAICD_VMC.ASC | |- EAICD_VMC.LBL | |- MEX-ESA-VMC_FLIGHT_MANUAL.DOC | |- MEX-ESA-VMC_FLIGHT_MANUAL.PDF | |- MEX-ESA-VMC_FLIGHT_MANUAL.LBL | |- VMC_DEBAYERING.PDF | |- VMC_DEBAYERING.LBL | ... | |- INDEX | | | |- INDXINFO.TXT Overview of directory | |- INDEX.LBL Label to INDEX.TAB | |- INDEX.TAB List of data file contents | ... | |- CALIB | | | |- DARK_2020.FIT Files used for | |- DARK_2020.LBL calibration and | |- FLAT_2020.FIT associated labels | |- FLAT_2020.LBL | ... | |- DATA | | | |- 2009 | |-200905 | |-20090507_0837_0907 | |-20090509_0853_0922 | | ... | |-200907 | | ... | |- 2010 | |-201001 | |-20100102_1339_1408 | |-20100104_1321_1343 | | ... | |-201002 | | ... | |- BROWSE | | | |- 2009 | |-200905 | |-20090507_0837_0907 | |-20090509_0853_0922 | | ... | |-200907 | | ... | |- 2010 | |-201001 | |-20100102_1339_1408 | |-20100104_1321_1343 | | ... | |-201002 | | ... | |- 2011 | |-201101 | |-20110101_2016_2047 | |-20110110_0337_0436 | |-201103 | | ... | |- 2012 | |-201205 | |-20120506_0037_0110 | |-20120519_0312_0344 | |-201206 | | ... ====================================================================== FILE FORMATS ====================================================================== VMC Level 3 calibrated DATA products are archived as a FITS data product with extension FIT. The FITS data product consists of a header and 2 layers. The first layer includes the calibrated values, and the second layer includes the raw values. The raw layer is not debayered, instead it contains only one channel, and is codified as unsigned integers of 8 bits. The calibrated layer is debayered, it consists of 3 channels and the codification is float32. For further information, please consult the EAICD document in the DOCUMENT folder. The VMC Level 3 BROWSE products are PNG files which are a direct conversion of the data product into an image with the Bayer pattern solved. Thus they contain 3 colour channels of 8 bits each. The Level 3 BROWSE PNGs also have enhanced colour and a sharpening filter; for details please see the EAICD document in the DOCUMENT folder. These products also each have an associated label file. ====================================================================== CONTACT INFORMATION: ====================================================================== The persons most directly responsible for the support of this data set are : Alejandro Cardesin-Moinelo European Space Astronomy Centre Urb.
