Pixel corners in HEALPix

Post by francisco bordin » June 09 2019

Hello to everyone,
I need to draw a sphere with a HEALPix pixelisation.

The function pix2vec_nest in the IDL library optionally renders cartesian vector coordinates of the pixel four vertices.

Unfortunately the same function in the C library doesn't do the same.

So I have just the center of the pixel. I've tried to understand the IDL code and add to the C library this option but it is hard, at least, for me.

Any idea?

thank you in advance.
