Could I have a data file or two? That way so I could try to walk
through what you did. I need to be able to reproduce the problem here
in front of myself in order to have a hope of fixing it.
It is certainly true that Athena is not completely reliable noticing
that chi(k) data is chi(k) data. You certainly should make sure the
data type is set correctly.
Thanks for taking the time to report the problem.
