Hi Chris,
>Is this using the "NRAO" version of ATLOD or the ATNF version???
This is a standard NRAO 31DEC09 installation, which includes ATLOD
5.3k in the distribution (I looked in ATLOD.FOR). As far as I can
tell 5.3k is the latest version of ATLOD present on the ATNF website.
So I don't think there is any difference.
