How to find the best fit of inner cut ellipse to points in polar plot?

vod vos 
hi,

1. How to find the best fit of  inner cut ellipse to points in polar plot?

2. How can we find the ellipse passing through  most of the points in polar plot?

And can we get the center x, center y, major radius, minor radius, and rotation angle of the ellipse?

The csv data is attached.

Thanks.
