Chapter 23
x cia reference guide
This chapter 1 completes the description, begun in Section 13.3, of x cia. It includes a description
of the advanced features of x cia and a useful reference guide to x cia’s commands.
23.1 Advanced use of x cia
Two advanced features of x cia are described in the following sections.
23.1.1 Executing IDL commands from within x cia
It is possible to execute directly an IDL command in the CIA Command Line window of the
x cia screen. You will be prompted in the message window if the command has been correctly
executed. Note that the result of the IDL command is visible either in the IDL window from
which x cia was launched or in a graphics window. This was mainly designed to display or plot
some interesting fields of the PDS structure without quitting x cia session. It can also be useful
to modify manually some fields of the PDS structure, such as the coordinates or the mask. See
Section 15.5 for more details on the architecture of the PDS.
23.1.2 Buffer variables
Three variables can be used as buffers: DUMMY, TEMP and OLD. At the beginning of the
session, they are initialized to zero but can contain any kind of data (including part of the PDS
structure). Temporary results can be stored in them, in order for example to plot the difference
between the latest result and an older one.
23.2 Help on x cia
23.2.1 List of commands
