non-linear curve fitting tool in grace returns rms relative error instead of rms percentage error

[Alex Valavanis]

Binary package hint: grace

The non-linear curve fitting tool in grace outputs the wrong value next to "RMS per cent error:" It actually gives the RMS **relative** error, i.e. it is out by a factor of exactly 100.

The RMS per cent error should be given as:

e = 100 * (y'-y)^2/y^2

Thanks for taking the time to report this bug and including a patch for it too. This package is sync'ed with Debian, subsequently it'd be quite helpful if you were to submit this bug and your patch upstream to Debian. You can learn more about how to forward bugs to Debian at https://wiki.ubuntu.com/Debian/Bugs.

I realize you've also forward this directly to upstream which is great too! If we could get this into Debian or Debian to update from upstream that it would be one less diff that Ubuntu would have to carry. Thanks!

I've made a report to Debian. Please could someone check that I haven't messed it up? :)
