This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

Data Set Abstract This data set includes sub-sampled versions of Viking Orbiter images that are intended to facilitate rapid viewing of the image collection. The image data in these browse images have been reduced in size by sub-sampling the original image by a factor of 4 in both lines and samples. Thus, the data volume has been reduced by a factor of 16. A Viking Orbiter browse image contains 264 lines and 300 samples. A filtering procedure was used in generating the browse images because Viking Orbiter images commonly contain noisy data or are missing data. The brightness value of a pixel in a browse image is the median brightness value of an array of 4 by 4 pixels from the original image. If the 4 by 4 array of original pixels contained zero values, those zero value pixels were not used in determining the median value. Of course, if the entire 4 by 4 array contained zero value pixels, the corresponding pixel in the browse image was assigned a zero value.
