FOCUS

FOCUS is used in VLBA test observations to specify an increment to the focus value used for the subreflector position. This is added to the nominal position known by the on-line system for the particular receiver.

Note that the schedule requires focus values in mm while tsm reports focus achieved in cm.

• Argument: A focus position in mm.
• Options: Any focus positon.
• Default: 0.0
• Usage: Default to previous scan.
• Example: FOCUS = 98.5
