Curved-sky information.
This structure contains all the information defining a given full-sky patch. It describes either a HEALPix grid (in which case is_healpix!=0) or a CAR patch (for is_healpix==0). If the latter, then the CAR pixelization must conform to the Clenshaw-Curtis sampling. In this case the colatitude theta must be sampled at N points going from 0 to pi (including both), separated by an interval Dtheta = pi/(N-1). Not all iso-latitude rings must be stored in the patch (i.e. ny!=N necessarily). See the documentation for nmt_curvedsky_info_alloc for further information on the constraints that some of the members of this structure must fulfill.
