Thanks, I understand now that in libproj, the plane MUST be orthogonal
to the earth, and there is no support for this plane to be "inside" the
Is there a way to use the library for this case ? by playing with parameters
what are the rest of parameters like lat_ts and k?), or it is just not

I should say lon_0+180
