[AstroPy] Fitting a 2D Gaussian Model

I'm currently playing with the modeling module,
using models and fitting, and I have encountered difficulties
in how to understand the values of theta that the fit delivers.

I'm looping through several ellipticities, and I obtain theta angle values
that can bu up to a several hundred, even in negative values.

This is the code snippet to fit the gaussians is on this link.

The output I've got is pasted here:

Could someone help me to understand why is this happening?
As something intesting if I plot the true and fitted gaussian using
they look pretty similar.
