Context: tools

Synopsis

A tool to test the installation of the CIAO Calibration Database (CALDB)

Syntax

check_ciao_caldb

Description

The check_ciao_caldb tool allows users to easily check that the CIAO Calibration Database (CALDB) is installed correctly. It is intended to be used after installing or upgrading CIAO, or to help diagnose problems seen with other CIAO toos.

The tool only tests the basic installation, and so provides a quick and easy test. It does not perform the same verification steps as the chkcif tool from the FTOOLS package (as described on the Download the CIAO CALDB page), which should be used for a more thorough evaluation.

Tool behavior

As shown in the example below, the tool will print out some basic information on the CALDB installation, and then exit with a status value of 0 when the installation is correct. If there is a problem then an error message will be displayed and the exit status will be set to a non-zero value.

Availability

The check_ciao_caldb tool is part of the CIAO contributed scripts package which should have been included as part of the CIAO installation.

Example

unix% check_ciao_caldb

The tool accepts no arguments. If the Chandra CALDB is set up correctly then you should see something like the following:

CALDB environment variable = /soft/ciao-4.1/CALDB
        which is a link to = /soft/caldb41/
             CALDB version = 4.1.3
             relelase date = 2009-07-06T16:00:00
CALDB query completed successfully.

The actual output will vary depending on where, and what version, of the CALDB is installed.

NOTES

This tool is not an official part of the CIAO release but is made available as "contributed" software via the CIAO scripts page. Please see the installation instructions page for help on installing the package.

Bugs

See the bugs page on the CIAO website for an up-to-date listing of known bugs.
