•	**Phase**		:	2  
•	**Status**		: 	Draft	 
•	**Category**		: 	Unpack, Assemble, and Verification (C1)
•	**Recurrence**	: 	once at commissioning
•	**Duration**		: 	0.5 day
**Description**
•	Check the working of the internal NCPA routine (phase diversity + wollastone (DI-DBI))

**Prerequisites**
•	SCICAM cooled down.

**Procedure**
•	Run the Phase-diversity routine using the images taken with the SHARK-NIR internal calibration sources to measure the NCPA within (excluding the deployable arm)

**Success criteria**
* Internal NCPA routine works fine and the PSF shows improvement in its quality.

**Notes**

**LBTO support**
* Liquid Nitrogen refill is required in the cleanroom.
