PDS_VERSION_ID = PDS3 RECORD_TYPE = "STREAM" OBJECT = TEXT PUBLICATION_DATE = 2011-05-11 NOTE = "GEOMETRY directory contents" END_OBJECT = TEXT END GEOMETRY/ Directory Contents ============================ This directory combines several top-level directories included in the original HAL_0019-23 disks: AST_HIST/ This directory contains and ancient ephemeris for Halley's Comet. EPHEM/ This directory contains the original ephemeris data in the format provided on the disks. Because undelimited text files present a challenge for many contemporary users, a delimited version of this file with a modern PDS3 label has been added. As with the contents of the DOCUMENT/ directory, these files were copied from the HAL_0023 disk, in order to have the last, best versions.
