Asking the latitude and longitude directly beneath the Sun causes inverse_terra not to converge, because the convergence increment `W` never got below 1.48e-8, but the convergence limit was 1.0e-8. I increased the limit to 2.0e-8 in all programming language versions. I'm hoping that is a big enough tolerance for all cases now, but I will do more testing to see if further fixes are required for even more distant bodies than the Sun.
