[daip] Re: aips DA=jansky

[Daniel Johannsson]

That answers the question even before I could type it out in more detail.
Are there any other options for data sharing between Solaris/Sparc and
Linux/x86 aips systems then?  To just have aips read data from a remote
nfs filesystem without using the DA= method?

Thanks,

Dan Johannsson
