Imaging Data

NSSDCA ID: PSPA-00366

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1976-08-12 to 1978-06-24

Description

This data set consists of the Experiment Data Records (EDRs) for the approximately 26000 images obtained by the Viking 2 Orbiter TV experiment, stored on magnetic tapes. The EDRs consist of unprocessed (raw) instrument data in VICAR format. Each image file consists of 53 blocks, containing 32000 bytes per block. Each block is composed of 20 logical records of 1600 bytes each. The first two logical records of the first block contain a label. The label is followed by 1056 logical records (one per image line) containing pixel and engineering data. Details of the data set are provided by Martin et al., "Planetary Image Conversion Task: Final Report," JPL Publication 85-50, 1985, which is available at NSSDC. This publication includes the only catalog currently available for the data set. The catalog lists images by Picno., an image sequence number, against tape/file position. For this reason, it is necessary to be able to identify the Picnos. of interest before placing an order.
