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?
HI, I suppose that +0 means that you have no shift of the energy between spectra, do you do the align before merging? and I suggest to merge in unnormalized spectra, sometimes I have "blocked" windows with pre- and post-edge parameters... darek
