A number of auxilliary processes can be running in addition to the main loop operation.

Extract WFS modes

Launches script ./auxscripts/modesextractwfs :

!INCLUDE "../scripts/auxscripts/modesextractwfs"

Converts WFS residuals into modes.

Extract open loop modes

Launches script C function (CPU-based):

key       :    aolcompolm
module    :    AOloopControl.c
info      :    compute open loop mode values
syntax    :    <loop #>
example   :    aolcompolm 2
C call    :    long AOloopControl_ComputeOpenLoopModes(long loop)

This function is entirely modal, and assumes that the WFS modes (see section above) are computed. The key input to the function is aolN_modeval, the WFS residual mode values. The function uses this telemetry and knowledge of loop gain and mult factor to track open loop mode values.

Optionally, it also includes aolN_modeval_pC, the predictive control mode values that are added to the correction in predictive mode.

Running average of dmC

Launches script ./auxscripts/aol_dmCave 0.0005 :

!INCLUDE "../scripts/auxscripts/aol_dmCave"

Compute and average wfsres

Launches script ./auxscripts/aolmkWFSres 0.0005 :

!INCLUDE "../scripts/auxscripts/aolmkWFSres"
