[Ifeffit] Athena merging question...

Hi Bruce and list,

I think I almost have a decent IFEFFIT script for my averaging problem.

However, while looking at the IFEFFIT command that Athena uses to
merge files I thought of a few questions.

When merging the energy scales of the various files, why did you
choose to use a quadratic interpolation rather than a linear or spline
interpolation?

Also, I notice that Athena sends a lot of commands that look like

set vpkr.energy = vpkr.energy+0
or
set yybe.merge = qinterp(yybe.energy+0, yybe.xmu, vpkr.energy)

to IFEFFIT when merging files.

What does the +0 do at the end of the array?  I've been looking
through the IFEFFIT documentation, but can't seem to find anything
that clarifies that command. Also, if I try and issue the command at
the IFEFFIT command line I get an error that reads "** cannot set
scalar value to array **".  So why can Athena issue the command and I
can't?

Thanks!

Matt
