== P3.10	NCPA working and performance == 
•	**Phase**		:	3  
•	**Status**		: 	Draft	 
•	**Category**		: 	Nighttime testing (functionality and operability) (C4)
•	**Recurrence**	: 	once at commissioning
•	**Duration**		: 	12 hours
**Description**
•	Evaluate the NCPA working and performance using the baseline approach, phase-diversity approach, combination of both, and measurement of NCPA using the Wollaston prison & dual-band imaging.

**Prerequisites**
•	Atmospheric conditions: ?
•	Authorize SHARK-NIR on the SX side.
•	AO working.
•	Target(s) at different Zenith distances with different magnitudes?

**Procedure**
•	Acquire star of given magnitude. Start SOUL-AO.
* Check the working and performance of the NCPA baseline approach. Take images at SCICAM.
* Check the phase diversity approach using Wollaston prism + DI-DBI. Take images at SCICAM.
* Check the phase diversity approach (using the internal calibration source). Take images at SCICAM.
* Repeat for a different star (of different magnitudes and for different elevation of the telescope)
