     39Running the program will create a ~/.asap directory which stores
     40some package state. From time to time you may have to clean this out,
     41after installing a new version of the package.

    4246.B ASAPDATA
    43 Path to astronomical ephemeris data files. These are needed to allow
    44 calculations of radial velocity, rest frequency of various transitions, etc.
     47ASAP needs access to astronomical data tables that need to be updated regularly.
     48These are needed to allow calculations of radial velocity, rest frequency of
     49various transitions, etc. The casacore packages that ASAP is built on top of
     50expect the data to be unpacked into this directory:
     51.RS
     52
     53/var/lib/casacore/data
     54
     55To this location you should set ASAPDATA so that the path
     56.NH
     57$ASAPDATA/ephemerides
     58.HY
     59exists.
    4560.PP
    46 They will usually be available in your installation of CASA.
    47 If your casa installation is at /nfs/casa, the ephemeris data should be
    48 in /nfs/casa/data; set ASAPDATA to that path.
     61The data files are published by the U.S. National Radio Astronomy Observatory
     62(NRAO), as part of the Common Astronomical Software Applications (CASA) data
     63processing package, but can be downloaded separately.
    4964.PP
    5065These data files can also be downloaded from

     72.B CASAPATH
     73The casacore routines ASAP is built on check for this environment variable
     74which is supposed to point to the CASA installation being used.
     75If CASAPATH is set in your environment, and it points to a
     76different data area than ASAPDATA, you may get unexpected behaviour.
     77If in doubt, unset it.
