Are the Viking Lander images available on CD-ROM?
No, not at this time. PDS is planning to put the images on CD-ROM for distribution sometime in the near future. However, Viking Lander images are available on-line through the PDS imaging node Viking Lander Image Browser. The Viking Lander images are also available from NSSDC in photographic or digital format. More information on CD-ROMs available from the NSSDC can be found in the NSSDC CD-ROM Catalog.

The visible filters were blue, green, and red multilayer interference filters which had very irregular spectral response, including a response to infrared light. Therefore, producing a “true” color image required the scene to be imaged in all six filters and an integrated spectral solution developed. The saturation levels at each wavelength also had to be estimated. Finally, with three visible filte
