d4scan

four-motor scan relative to the starting positions

SYNOPSIS

d4scan m1 start1 end1 m2 start2 end2 m3 start3 end3 m4 start4 end4 intervals time

DESCRIPTION

d4scan scans four motors, as specified by motor1, motor2, motor3 and motor4. 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.
