Fix derivatives when calling with the transit structure #41

Closed ericagol closed 6 years ago

ericagol commented 6 years ago

[x] There is an error which occurs when computing derivatives with the transit structure; probably some array is not being set to zero (as in the total flux case).

ericagol commented 6 years ago

It turns out that the grad variable in the transit structure was set to false. Also, in the cases when flux is zero or one, I was not returning zero gradients.

This has been fixed in the master branch, so closing for now.
