      The formula is quite simple:

      2 * equirect width * tan(FoV/4) / pi

      The result is the stereographic image width and "FoV" is the angle of
      the desired field of view of the stereographic image.

      However, Pano2VR most likely doesn't use this mapping but the fisheye
      one, where the output image width is the same as the equirect image width.
