Examples of gov.fnal.eag.healpix.PixTools.query_polygon()

gov.fnal.eag.healpix.PixTools.query_polygon()
finds pixels that lie within a CONVEX polygon defined by its vertex on sphere @param nside the map resolution @param vlist ArrayList of vectors defining the polygin vertices @param nest if set to 1 use NESTED scheme @param inclusive if set 1 returns all pixels crossed by polygon boundaries @return ArrayList of pixelsalgorithm: the polygon is divided into triangles vertex 0 belongs to all triangles @throws IllegalArgumentException

    vlist.add((Object) v);
    v = pt.pix2vect_ring(nside, 86);
    vlist.add((Object) v);


    ArrayList pixlist;
    pixlist = pt.query_polygon(nside, vlist, nest, inclusive);
    //    System.out.println(" List size="+pixlist.size());
    int nlist = pixlist.size();
    //    System.out.println(" Pixel list:");
    for (int i = 0; i < nlist; i++) {
      ipix = ((Long) pixlist.get(i)).longValue();
