dm_influ_to_fits_hdu()

def common.fits.dm_influ_to_fits_hdu	(		sup,
			dm_id,
		*	influ_index = -1
	)

Return a fits Header Data Unit (HDU) holding the influence functions of a specific DM.

Parameters

sup	(compasSSupervisor) : supervisor
wfs_id	(int) : index of the DM in the supervisor
influ_index	(int) : (optional) default -1, index of the actuator to get the influence function from. -1 : get all influence functions

Returns

hdu (ImageHDU) : hdu holding the DM influence functions

write_data()

def common.fits.write_data	(		file_name,
			sup,
		*	wfss_indices = None,
			dms_indices = None,
			controller_id = 0,
			influ = 0,
			compose_type = "controller"
	)

Write data for yao compatibility.

write into a single fits:

• number of valide subapertures
• number of actuators
• subapertures position (2-dim array x,y) in meters centered
• actuator position (2-dim array x,y) in pixels starting from 0
• interaction matrix (2*nSubap , nactu)
• command matrix (nacy , 2*nSubap)

Parameters

file_name	(str) : data file name
sup	(compasSSupervisor) : supervisor

Kargs

wfss_indices (list[int]) : optional, default all, list of the wfs indices to include

dms_indices (list[int]) : optional, default all, list of the DM indices to include

controller_id (int) : optional, index of the controller passed to yao

influ (int) : optional, actuator index for the influence function

compose_type (str) : optional, possibility to specify split tomography case ("controller" or "splitTomo")
