Parameter Files

In order to accomodate the new Parameter Editor GUI (Peg), filename parameters in all parameter files have been changed from type 's' to type 'f'. Since all files have been modified, users should delete all their old parameter files before running CIAO 3.0.

Datamodel

The CXC Datamodel library, which underlies CIAO's data I/O and filtering capabilities, has been completely rewritten for greater efficiency and maintainability. The new structure will make it easier for us to add new capabilities, but in CIAO3.0 the behaviour should be essentially identical.

Libraries

Note that some of the changes listed in this section were also included in the CIAO 2.3 patch. However, in that release, the library changes applied only to the tools that were patched. In CIAO 3.0, the changes now apply to all of CIAO.

ardlib

caldb lib

cxcparam

dmtlib

dslib

errlib

grplib

hdrlib

histlib

mtllibs

pixlib

psflib

region lib

stack lib

tcdlib


S-Lang Modules

CIAO contains many libraries of code that perform 'under-the-hood' tasks, such as interpreting parameter files, converting between coordinate systems, and so on. CIAO 3.0 is the first release where many of these libraries now can be called from S-lang directly. Advanced users can develop tools for their specific needs using these libraries. Some CIAO 3.0 tools are already written in S-lang using these libraries, e.g. acis_fef_lookup, and more are expected.
