What do the file names for the images and directories on the Viking Orbiter CD-ROMs mean?
Images on the Mission to Mars: Viking Orbiter Images of Mars CD-ROMs (volumes VO_10xx) are given a designation of the form FxxxZyy, where xxx is a three digit number indicating the orbit number, Z is a capital letter indicating the mission: A and S are Viking Orbiter 1, B is Viking Orbiter 2, C and D indicate images taken by Viking 1 and 2 respectively before orbit insertion, X and Y indicate Viking Orbiter 1 and 2 images, respectively, acquired in an orbit with more than 100 images. The last 2 digits, yy, give the sequential number of an image taken within a given orbit. For example, F443A10 is the 10th Viking 1 image taken on orbit 443; F004Y01 is the 100th Viking 2 image taken on orbit 4. • Are there CD-ROMs available for any of the other Viking experiments? Yes, the Viking Orbiter 1 and 2 Infrared Thermal Mapper (IRTM) data are available on CD-ROM from the Planetary Data System. • Are the Viking Lander images available on CD-ROM? No, not at this time. PDS is planning to put the ima
