<P>The IRA Continuum window is used to show a stripchart-like display
of incoming values from the two-port (East <I>X</I> West) correlation
function. The plot shows correlation intensities in the Y axis, and
time in the X axis.</P>

Postscript</I></FONT></FONT></P>
<P STYLE="font-style: normal">This pushbutton control allows you to
make a postscript file of the current stripchart display. It will
pop-up a file-browser to allow you to select a filename and directory
for the resulting <I>PostScript</I> file.</P>
<P><I>DISMISS</I></P>
<P>This button control causes the IRA Interferometer window to close.
Even though the window is closed, new data are continuously added to
the stripchart. The window may be brought back by using the
corresponding “Show” button in the IRA Control window, in the
Continuum area.</P>
<P><I>LMST Fields</I></P>
<P>There are 2 fields above the stripchart that show the approximate
LMST that corresponds to that X position on the strip chart.</P>
