== P3.5	Check the acquisition **Procedure** == 
•	**Phase**		:	3  
•	**Status**		: 	Draft	 
•	**Category**		: 	Nighttime testing (functionality and operability) (C4)
•	**Recurrence**	: 	once at commissioning
•	**Duration**		: 	1 hour(s)
**Description**
•	Verify the acquisition sequence for SHARK-NIR
**Prerequisites**
•	Atmospheric conditions: should be able to see bight stars on sky (preferably close to zenith?).
•	Authorize SHARK-NIR on the SX side.
•	Suitable bright enough target (including the possibility of performing AO).
**Procedure**
•	Start the acquisition sequence: collimating the telescope to reduce the aberrations, close the loop and produce better ASM flat, NCPA estimation using phase-diversity algorithm, close SHARK-NIR tip-tilt+NCPA loop, and check the PSF quality at SCICAM. 
•	Save telemetry (open and closed loop of the ALPAO DM).
**Success criteria**
•	Successful acquisition sequence.
**Notes**
**LBTO support**
•	Support from LBTI/LBTO?
•	Presence of John Hill usually helps while collimating for first time. 
•	Steve Allenson (as the TO) will be a great asset too.
**Associated SHARK-NIR personnel**
•	JF, LM, MdP, MM (from AZ), DV?
