d3scan

three-motor scan relative to the starting positions

SYNOPSIS

d3scan m1 start1 end1 m2 start2 end2 m3 start3 end3 intervals time

DESCRIPTION

d3scan scans three motors, as specified by motor1, motor2 and motor3. Each motor moves the same number of intervals. If each motor is at a position X before the scan begins, it will be scanned from X+start to X+end. The step size for each motor is (start-end)/intervals. The number of data points collected will be intervals+1. Count time is given by time, which if positive, specifies seconds and if negative, specifies monitor counts.

Upon termination, the motors are returned to their starting positions.
