The data areas are chosen in what is a fairly complicated
manner.  The basic plan is to read DADEVS.LIST from
multiple possible places, the most fundamental of which
is $AIPS_ROOT/DA00.  Your installation will have this
file set up by install.pl.  It looks like

-  /DATA/AAKASH_1
-  /DATA/AAKASH_2
-  /DATA/AAKASH_3
-  /DATA/ALFIRK_1
-  /DATA/ALFIRK_2
-  /DATA/ALIOTH_1
-  /DATA/AMIGO_1
-  /DATA/ARARAT_1
-  /DATA/ARARAT_2
-  /DATA/ARARAT_3
-  /DATA/ARARAT_4
-  /DATA/ARARAT_5
-  /DATA/AZGEDA_1
-  /DATA/BANANA

where the format is strict: minus sign, two blanks, directory name
which can be anything.  When a user starts up on some machine,
for example, AMIGO, the file is read and any data area having the
string AMIGO in it is included (and all others with - signs are
ignored).

To make things simpler and more flexible for users, another file
names $HOME/.dadevs.always is read first.  All directories in the
file (that are not commented out) are included every time the
user runs AIPS no matter what is in the directory name.  Any
with + in column one is included first, then any extra from the
basic DADEVS.LIST file, and then the rest of the .dadevs.always.  My
$HOME/.dadevs.always looks like

+  /.lustre/aoc/users/egreisen/AIPS/LUSTRE_1
-  /DATA/PRIMATE_1
-  /DATA/PRIMATE_2
-  /DATA/PRIMATE_3
-  /DATA/PRIMATE_4
-  /DATA/PRIMATE_5
-  /.lustre/aoc/users/egreisen/AIPS/LUSTRE_2
# +  /stash/users/fowen/AIPS
# +  /DATA/ARARAT_3
-  /.lustre/aoc/users/rperley/AIPS/LUSTRE_1

I have my Lustre 1 area with a + so that my AIPS 1 disk (which
has all sorts of control files) is always the same no matter
what computer I am on.  My desktop (PRIMATE) is also always
included.

There is one other gotcha.  Any AIPS data area must include a file
named SPACE which is usually just a 0-byte file made with touch.
This file is used in file creation to make sure that the creation
does not encounter conflicts.  It should have pretty open privileges.

Does this help?
