Abstract :
We examined recent multi-pole measurements for the helical snakes and rotators in RHIC to generate a full field map. Since multi-pole measurements yield real field values for BP field components we developed a unique technique to evaluate the full fields using a traditional finite element analysis software. From these measurements we employed SNIG to generate orbit and Spin plots. From orbit values we generated a transfer matrix for the first snake
