30<div class="fragment"><pre class="comment">PLOTCOD Closed Orbit Distortion
31 PLOTCOD(RING,DP) finds and plots closed orbit for a given momentum
32  deviation DP. It calls FINDORBIT4 which assumes a lattice
33  with NO accelerating cavities and NO radiation
34
35  INPUTS
36  1. RING - At structure
37  2. DP   - Energy offset
38
39  OUTPUTS (Optional)
40  1. orbit - (x,px,y,py) closed orbit along the ring
