Re: descriptor file and changing scale_factor

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Sophie,
Ferret currently applies the same factors to all of the stepfiles
used by a descriptor file. There is not a way around this now.
We just ran into this with another user, and it turns out that the
it's not hard to keep track of separate scaling for each file.  Watch
for this in the next release of Ferret.
