 AIPS can be started by running the command ''​aips''​. There is a small deviation from a standard AIPS setup here: AIPS can be started by running the command ''​aips''​. There is a small deviation from a standard AIPS setup here:
-  * If environment variable ''​$FITS''​ is set, its value is preserved, in stead of pointing to a location in ''​$AIPS_ROOT''​ which should ​then be writable ​by all users.+  * If environment variable ''​$FITS''​ is set, its value is preserved, in stead of pointing to a location in ''​$AIPS_ROOT'' ​(which would then need to be writeable ​by all users).
   * All computers have a local directory ''/​data1/​DA00''​ and the variable ''​$DA00''​ is made to point there.\\   * All computers have a local directory ''/​data1/​DA00''​ and the variable ''​$DA00''​ is made to point there.\\
 So please be aware that if you bypass our startup script to call ''​STARTAIPS.SH''​ directly, you will loose this setup, and all tasks will run very slow, because all ''​DA00''​ files will live on a disk on a central server. So please be aware that if you bypass our startup script to call ''​STARTAIPS.SH''​ directly, you will loose this setup, and all tasks will run very slow, because all ''​DA00''​ files will live on a disk on a central server.

 +===== AIPS number ===== 
 +Since all data resides in your own directories,​ the aips number asked at startup is something you can choose yourself. You don't have to coordinate your user number with others or with system management. Note that number 0 is special, used by aips startup and some internal tasks.
