mpfit2dpeak and fitting an ellipse [message #60614]

Hello,

I have a quick question regarding fitting routines. I will describe
the problem first.
I have an image with X,Y coordinates and I try to find an overdensity
of points
by smoothing out the image. I used mpfit2dpeak to fit the N number of
points
and I was able to find the center xcen and ycen that way. But the
mpfit2dpeak
assumes either a Gaussian,Lorentzian or Moffat function. The shape
that I am
looking for in the image is an ellipse so I was looking if there is an
available
program that fits a 2 dimensional ellipse but I could not find one.
Does anyone have any suggestions on how to handle this?

Thank you,
Kevin Pallati
