The contour plot of the Kent distribution on the sphere for some data is produced.

`x` |
A two column matrix, where the first column is the latitude and the second comlumn is the longitude. If the matrix has two columns, it is assumed to have unit vectors and in this case it is turned into latitude and longitude. |

MLE of the parameters of the Kent distribution are calculated, then the contour plot is plotted using these estimates and finally the data are also plotted.

A plot containing the contours of the distribution along with the data.
