Before you can use AIPS under SunOS for the first time, you must request from the system administrators that your account be added to the list of users allowed access to the AIPS data files.

You should use your UNIX user ID as your default AIPS user number. (Typing:

	echo $uid
on the UNIX command line will tell you what your userid is.)

You should always remember what user number you are using, as it will be needed for future access to your AIPS data.

If you need to access private AIPS data disks as well, you will have to use one of the user numbers listed in /usr/local/pkg/aips/DA00/NETSP. (Only the system administrators can add new AIPS user numbers to that table.) Presumably, the owner of the private disk can tell you which numbers may be used or not.

Effective 2003-01-13, if you want to run AIPS on a computer that does not have any user areas on its disks, you need to start it with the command:

	aips da=SOMEHOST
where SOMEHOST is the name of a computer that does (e.g., public for the disks accessible to anyone), or it will abort at startup.

Note that this means that your disk selection listing will change depending on what computer you run AIPS from, even if there has been no actual change in the disks available over the network.

On some systems you need to add the following line to your ~/.Xdefaults (or equivalent):

	AIPStv*useSharedMemory: 0
if you get a display/shared memory error message.

(You may need to activate this setting by typing:

	xrdb ~/.Xdefaults
after editing that file--or creating it if it didn't already exist.)

Only one (or maybe two?) AIPS or TV process(es) can run at the same time on the same computer, so if someone is already running an instance, you should choose another system to run yours.
