Overview

As input, no parameters are required. However an optional input parameter (dspace_check) will force the script to perform disk space checks prior to uncompression and untarring of each file. If omitted no checks performed!

For each tar file the script then:

• Uncompresses and untars the file
• Creates the appropriate directory structures
• Populates the directory tree with files
• Moves the /data/tarredcif to data/{mission}/{instrument}/caldb.indx (if NOT caldb_setup_files.tar!).
• Edits the appropriate CALDB initialisation files such that the line which defines the environment variable CALDB points to the top=level directory of the local CALDB.

Each compressed tar file for a given mission/instrument contains :

• ./data/{mission}/{instrument}/../../calfilenames
• ./data/tarredcif (the caldb.indx file for the {mission}/{instrument}).
• ** ./data/{missn}/{instr}/goodfiles_{missn}_{instr}_special.ASCII (list of all good quality cal files within the caldb.indx together with last-modification-date info ....this ASCII file is necessary to perform any future up-dates to the local caldb.indx of a HEASARC-supported mission but with personal/locally produced datasets added).
• ** ./data/input.ASCII (contains 4 lines..{mission};{instrment}, {instrument alias}; name of special ASCII file).

The file caldb_setup_files.tar.Z contains :

• ./software/tools/caldbinit.unix (for initialising environment variables or unix-style systems running FTOOLS outside IRAF).
• ./software/tools/caldbinit_iraf.unix file (for initialising environment variables for unix-style systems running FTOOLS from within IRAF).
• ./software/tools/caldbinit.sh (for initialising environment variables in Bourneshell).
• ./software/tools/caldb.config file (to indicate the location of caldb.indx files).
• ./software/tools/alias_config.fits file (for instrument alias info).
