I'd define the 45 ° limit in a named constant on top, something like FOV_ANGULAR_DISTANCE_LIMIT = 45 * u.deg and then compare to FOV_ANGULAR_DISTANCE_LIMIT.to_value(u.rad) instead of multiplying both sides with the unit (faster).
Maybe you can also put this part into a function so it looks like this:
if far_outside_fov(src_fov_lat, src_fov_lon):
return INVALID

I'd make this private (i.e. add an underscore in front)

Fix for issue #2264. Events with large reconstructed angular distances from the camera center now return the INVALID container.
