This directory contains a cumulative index table (CUM_INDX.TAB) which
describes the location of all files on the PV02 collection (PVO-OIMS).
In addition, there is a file (INDEX.TAB) which gives the name, associated
dataset and location of all files on this volume. These index files have been
provided for database users who do not wish to make use of the DITDOS
software. The file is an ascii table whose columns are comma separated which
should facilitate loading into most spreadsheet or database programs. The
index file INDEX.TAB is accompanied by a label and format file.
