This routine used to be called dpper, but the 115 * functions inside weren't well organized. 116 * 117 * References: 118 * 119 * NORAD Spacetrack Report #3 1980 120 * Hoots, Roehrich 121 * 122 * NORAD Spacetrack Report #6 1986 123 * Hoots 124 * 125 * Hoots, Schumacher and Glover 2004 126 * 127 * Revisting Spacetrack Report #3 128 * Vallado, David, Crawford, Paul, Hujsak, Richard, Kelso, T.S. 129 * AIAA 2006-6753 130 * 131 * This revision: 132 * 133 * 2008 April 6 134 * 135 * Copyright (C) 2008 Paul C.
