We describe the method for identifying and classifying the emission-line sources and the procedure for computing their J2000 coordinates and velocities. The number of PN detections and the errors in the velocity measurements (37km/s) indicate that this technique is comparable to other methods. **************************************************************************** * * * The PN line-of-sight velocities will be published with a * * subsequent paper that also includes dynamical models of the system. * * * **************************************************************************** File Summary:
