Function Documentation

calculate_SE_displacement()

def HWS_Offload_Tip-Tilt2SE.calculate_SE_displacement

(

current_shape

)

Calcualtes the SE displacement for the current_shape (DM) passed. 
Returns the delX, delY values (displacement values for all the acquired SEs)
Note that this function make use of the already calibrated matrix.

displace_SEs()

def HWS_Offload_Tip-Tilt2SE.displace_SEs	(		delX,
			delY
	)

Displaces all the acquired SEs by the same delX, delY amount in Focalplane coordinates (in microns)
Note that all the other SEs do not move from their already existing position.
And that since the relative displacements we make (delX,delY) are very small, <200um, the collision is not anticipated.

get_Xinetics_tiptilt()

def HWS_Offload_Tip-Tilt2SE.get_Xinetics_tiptilt

(

)

Function that will connect to ringbuffer, extract 1000 dmCommands spread across 1 min.
The average shape of the DM is returned.
