Column definition in Chandra event files
The following show the available options for setting the event
definition for the Chandra event processing tools (acis_process_events,
hrc_process_events, and tg_resolve_events).
The "Data Products" Guide - available from the
CIAO manuals page -
contains a detailed explanation of the columns.
The meaning of the DataType column is given below.
