A summary of supporting and secondary databases and the approximate size is provided in the following table. Certain database sets are automatically included when a Software installation or full upgrade is performed (described in previous section). All database files are also available on Exabyte tape (``ydb tape'') To receive a tape containing the mission-long Yohkoh database and to be placed on the distribution list for future releases, send e-mail:
TO: software@isass0.solar.isas.ac.jp
SUBJ: ydb tape request
The IDL routine RD_YDBTAP (described in the User's Guide) can be used to extract and install user specified portions (or all) of the Yohkoh database from the ydb tape. That routine will optionally provide assistance in setting up and customizing the local environment prior to extraction and installation. The physical disk locations where each database resides at any given site are flexible since all software references are through the use of environmentals (Unix) or logicals (VMS). The IDL routine HELP_PREFIX provides some additional information about the specific database contents.
This table can be used to estimate current and future disk space requirements for the Yohkoh database. Unless otherwise noted, the distributed files contain one week of data. Column one (PFX) indicates the three letter prefix associated with each database set. Items marked with an asterisk are included in the automatic software installation procedure described in the preceding sections.
