Yes. It's the default fov (don't ask me why the default value is 41) for projections for which it's not specified.
Ok I see the script parameters but what is 41? is it fov?
The arguments in the 2d-to-3d conversion script are the same as in d3d_set_projection_ext without znear and zfar (the last two). In case there happens to be a problem using the script, here is an example about it.
