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

gov.fnal.eag.healpix.PixTools.query_disc()
generates in the RING or NESTED scheme all pixels that lies within an angular distance Radius of the center. @param nside long map resolution @param vector Vector3d pointing to the disc center @param radius double angular radius of the disk (in RADIAN ) @param nest int 0 (default) if output is in RING scheme, if set to 1 output is in NESTED @param inclusive int 0 (default) only pixsels whose center lie in the triangle are listed, if set to 1, all pixels overlapping the triangle are listed @return ArrayList of pixel numberscalls: RingNum(nside, ir) InRing(nside, iz, phi0, dphi,nest)
