Hi All,
The help for kappa collapse with estimator iwc states "Iwc" --
Intensity-weighted co-ordinate, being the sum of each value times its
co-ordinate, all divided by the integrated value (see the "Integ" option).
How does it do this? I would like to create a 3D cube, the same size as
my original cube, but whose data values are the intensity multiplied by
the velocity coordinate for each velocity channel.
So, basically I would like each value times its coordinate, without any
summing. This may well be a simple task, but the method is currently
escaping me.
cheers,
Jane
