What is a "standard" CIAO installation?
The CIAO threads assume that all of the "standard" CIAO components have been downloaded and installed: tools, ChIPS, Sherpa, prism, the Scripts Package, and the CALDB.
If you have installed a customized version of CIAO, it is possible that some of the analysis tasks will fail due to a missing package. Similarly, the scripts may contain a dependency on any of the other standard components, and will fail if one is missing.
