Important Notes for 90prime Observers.

1. Starting the Guider:
	On the operators left computer click on the Telcom Server icon.
This will start communications with the telescope.
	Click on the AzCam Server to start communications between the
the camera server and the computer.
	Click on the SO Guider.tcl icon.  This will start the guider
software.

2. Starting the AzCam Tool:
	The rack mounted 90PRIMECCD (BOKPC2?) should be running.
	The 90prime Cserver should be running on the desktop (this is
the replacement for the AzCam Server).
	Click on the AzCam Tool icon in the upper right hand corner
of the desktop.
	That brings up a configuration file window "AzCam Configuration".
	The default file is 90prime.ini but you can also "Select..." 
Devices in the ring menu, choose 90prime.
	Click on the "Read" button.
	Click on "Exit"
	A window will appear briefly while the GUI connects to the server.
	Set the detector binning.  Click on "Detector".  In the "Readout
Format" tab click on column bin and row bin to set them to your desired 
binning. Click on "Set Formats" and then "Exit".
	Change the filename to make sure data is transfered to stjukshon 
properly.  In the main AzCam Tool click on "Change Filename".  The 
directory "Z:" points to stjukshon:/data/bokobs/.  Use the folder button
to select a folder on stjukshon.  The sub-directory must exist on
stjukshon or you must first "mkdir" to create it.  You'll need to
enter a username and password at this point; if you don't know it call Ed.
	In the same window you can change the root name and the sequence
number for your data.  As a typical set-up choose "Auto Increment Sequence"
and "Include Sequence Number".  "Auto Name" uses the root name and the
image type in the filename.  The filename corresponding to your set-up
will display at the bottom of that window. Click "Exit".
	Make sure "Save Image" is selected in the main AzCam window.
	Click on "Preferences".  In addition to the default preferences
you may want to choose "Prompt for Image Title".  Alternatively you
can type the image title in the main AzCam window.  Do NOT choose
"Display with ds9" because you'll be viewing the data on stjukshon. In
the "Parameters" tab set the number of images to observe in a sequence
of exposures (focus sequence, n consecutive exposures of a specific type).
More information about sequences is given in the discussion on exposures.
	Take an exposure.  Click on "Image Type" to select image type.
Select exposure time with the increment buttons or by highlighting and
replacing hours, minutes, and/or seconds.  Click on "Expose".  The
progress bar and the 90prime Cserver will display the progress.  The 
data is assembled on the CCD computer but saved only to stjukshon. 
	
	To take sequence of images:
	If you pick image type "focus" it automatically starts a
sequence which is actually a multiple shifted exposure on one image.
More information is provided in the focus discussion below.  For any 
other image type such as "zeros", choose "Sequence" and then "Expose".
The "Messages" window shows the current image number in the sequence. 
To stop a sequence 
	During an exposure you can hit the "Pause" button (which replaces
the "Expose" button) to pause an exposure.  You can then either "Resume"
to continue the exposure, "Stop" to truncate the exposure, or "Abort" 
to abort the exposure.
	You can only edit text in yellow text boxes.

3. There are 5.29 microns per focus step.  Typical focus increments of 
50 are good to use for a very coarse focus sequence and 20 or 25 (depending
on seeing) for a fine sequence.  A crucial test for focus is whether you
see any astigmatism (residual in the system).

4. To put an object in the guide camera:
	From 3993, 3868 on chip 1
	offset 328 arcsec west
	and 3123 arcsec North
	to center the object in the guider.
