List of ang2pix_nest() Examples

Examples of ang2pix_nest()

gov.fnal.eag.healpix.PixTools.ang2pix_nest()
renders the pixel number pix (NESTED scheme) for a pixel which contains a point on a sphere at coordinates theta and phi, given map resolution parameter nside. The computation is made to the highest resolution available and then degraded to requared resolution by integer division. It makes sure that the treatment of roun-off will be consistent for every resolution. @param nside the map resolution parameter @param theta double theta coordinate @param phi double phi coordinate @return pixel number long @throws IllegalArgumentException

Examples of gov.fnal.eag.healpix.PixTools.ang2pix_nest()

    Vector3d v = pt.Ang2Vec(theta,phi);
    long pix1 =  pt.vect2pix_ring(nside,v);
    assertEquals("pix=" + pix, pix1, pix, 1e-10);
    assertEquals("pix=" + pix, 76, pix, 1e-10);


    long pix2 =  pt.ang2pix_nest(nside,theta,phi);
    long pix3 =  pt.vect2pix_nest(nside,v);
//    assertEquals("pix2=" + pix2, pix3, pix2, 1e-10);
//    assertEquals("pix2=" + pix2, 92, pix2, 1e-10);
