The Low Bandwidth Wavefront Sensor (LBWFS) Manager (LBMngr) is
a display tool for the AO operator to monitor and control how the
LBWFS data are applied to the AO correction.
Overview
Focus/COG control
Plot of focus and RMS wavefront error
Processed image display and calculated parameters
Reconstructed wavefronts
GUI Description
FOCUS CONTROL
Radio button turns on/off LBWFS focus control.
Color box on right hand side of GUI turns GREEN = on,
or RED = off.
Sets LBWFS focus control off
Sets use COG to focus off
Zeros the LBWFS focus contribution
Set focus gain to max (currently 1.00)
Set DM focus offload off
Update Na altitude
Set focus gain to mid-range (currently 0.5)
Set DM focus offload on
Set DM focus offload timer to every 120 sec
Editable box, values: 0.0-1.0.

COG CONTROL
Radio button turns on/off LBWFS cog control.
Color box on right hand side of GUI turns GREEN = on,
or RED = off.
Set update COG off
Set use COG to focus off
Set cog gain to mid-range (currently 0.5)
Set leak to 0.95
Set cog gain to low-range (currently 0.3)
Set leak to 0.95
Editable box, values: 0.0-1.0.
