== P3.10	Check the acquisition procedure == 

- **Phase**		:	3  
- **Status**		: 	Draft	 
- **Category**	: 	Nighttime testing (functionality and operability) (C5)
- **Recurrence**	: 	once at commissioning
- **Duration**	: 	4 hours

**Description**
- Verify the acquisition sequence for SHARK-NIR

**Prerequisites**
- Atmospheric conditions: should be able to see bright stars in the 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).

**Templates**

**Success criteria**
- Successful acquisition sequence.
