\subsection{\xlabel{using_gaia_from_the_cshell}Using GAIA from the C-shell}

To display an image in GAIA use the following command
(assuming that you are already initialized to use Starlink software):
\begin{quote}
\mytt{\% gaia image\_name}
\end{quote}
Alternatively you can use the \mytt{File} menu to load an image.

If you want to display an image in an existing GAIA then use the
invocation:
\begin{quote}
\mytt{\% gaiadisp image\_name}
\end{quote}
You can also write to a specific window using the clone number:
\begin{quote}
\mytt{\% gaiadisp image\_name 2}
\end{quote}
This displays into the window with title \mytt{GAIA::SkyCat (2)}.
If this window doesn't exist it will be created.

A list of images can be displayed in GAIA using the command:
\begin{quote}
\mytt{\% gaiadisp image\_name1 image\_name2 image\_name3 ...}
\end{quote}
These will be displayed in separate clones. Finally percentile or
data cuts can be applied using the \mytt{-p} option or \mytt{-l} and 
\mytt{-h} options:
\begin{quote}
\mytt{\% gaiadisp -p 98 image\_name1 image\_name2 image\_name3 ...}
\end{quote}
\begin{quote}
\mytt{\% gaiadisp -l 100 -h 200 image\_name1 image\_name2 image\_name3 ...}
\end{quote}
(works for the single image case too).
