I didn't understand how to use the DIST_ELLIPSE though.

I typed
> IDL dist_ellipse, ellipse_distances, [300,300], x_center, y_center, 2.0

And I got the following:

Syntax - DIST_ELLIPSE, im, n, xc, yc, ratio, pos_ang, /DOUBLE
im - output elliptical mask image array
n - size of output image mask, scalar or 2 element vector
xc,yc - coordinates of ellipse center, scalars
ratio - ratio of major to minor axis of ellipse, scalar
pos_ang - position angle, counterclockwise from up

I didn't see how I'll get the distances from center using this function.
