Once past this hurdle, the astronomer will find several windows have been opened. On the left is a grey window labeled ``Data Acquisition" and on the right a white window labeled ``Data Reduction". IRAF is running in both of these windows, but different packages have been automatically loaded. (Note also that the parameter files are kept separately for the two windows; this has been known to cause some confusion.) You must run ICE/CCD commands from the ``Data Acquisition" window, and this window alone. An ximtool picture window will appear. Finally, you will find a number of icons appearing at the bottom: the console window, a clock, a cpu performance meter, ``xtapemon", ``Mosaic", and a ``Desktop". The console window will be open, and it is a good idea to check it from time-to-time; this is where any error messages (such as tape drive problems) will appear. Note, though, that you can not type into this window.
Beginning in the summer of 1994 we switched our window system from ``sunview" to an ``openwindow" (``X"-ish) system that differs only slightly from sunview. Most changes will be transparent. The new display window is now ``ximtool" and is even nicer than the old one: for more on using ``ximtool" see Sec. F. There is a guide called ``Notes for using X Windows on Kitt Peak" found in every dome; this will walk you through manipulating windows if you find you don't guess right. The rudimentary manipulations remain unchanged: To uncover a window move the mouse to the general area and press the L5 key. You can ``close" a window (not the same as quitting) by moving the mouse onto the window and hitting the L7 key. To open a window, place the mouse on the icon and hit L7. ``Double-clicking" on the closed icon will accomplish the same thing.
One very useful feature is the ability to change your Data Acquisition window or your Data Reduction window to a scrolling window, allowing you to pan up and see what it is you did previously. Simply place the mouse in the window, and hold down the CNTL key while pressing the right-most mouse button. Select ``Enable Scrollbar".
If you need to create a second Data Reduction window (because the first one is tied up doing something else) you can do this by moving the mouse to one of the blank areas, holding down the right-most mouse button, and selecting ``Data Reduction".
(You could also start IRAF from a ``Unix xgterm" window. However, because the parameter files are kept separately for the Data Acquisition task and the Data Reduction tasks, you would first need to do a cd reduce, followed by a cl followed by a cd to return to the main directory. If you ever start up IRAF and see the message ``Warning: no login.cl found in login directory", you're in trouble. Log out and start over.)
