How to average out the drifting circle?

I have X and Y coordinates of a drfting trajectory (oval). The are about 2.5 passages of the drfting trajectory (oval). I would like to obtain an averaged orbit of the trajectory.

The picture below shows the trajectory. The data coordinates are blue. I want a circle like Red one.

The data for X and Y is attached below.

Here is the code for blue circles:

load('matlab.mat')
subplot(211);
plot(Rgsm(1,:),Rgsm(2,:));

Any help is greatly appriciated. Thank you in advance!

You may consider using: https://in.mathworks.com/matlabcentral/fileexchange/3215-fit_ellipse

You need to read the coomments given in the function. Check the example shown in there.

Thank you for your valuable suggestions

load('matlab.mat')
x = Rgsm(1,:) ;
y = Rgsm(2,:) ;

plot(x,y,'.b')
hold on
ellipse_t = fit_ellipse(x,y,gcf) ;

Yes, That worked. Thank you so much @KSSV
