== P2.5	SOUL AO system test == 

- **Phase**		:	2  
- **Status**		: 	Draft	 
- **Category**	: 	Daytime testing (functionality and operability) (C3) + Daytime calibration (C4) 
- **Recurrence**	: 	after instrument installation at telescope platform
- **Duration**	: 	5 days

**Description**
- Proper working of the SOUL AO system is essential for the performance of the SHARK-NIR instrument. Arcetri team optimizes the SOUL AO system grabbing the PSF image from the SHARK-NIR SCICAM. The on-axis light source could be the Argos swing arm calibration light source, or one mounted on RR may be used (second choice only). 

**Prerequisites**
- SHARK-NIR is active and working normally.
- Cryostat cold and SCICAM working properly.
- Activity [wiki:/docs/CommissioningPlan/P1.12 P1.12] success criteria met.
- Telescope pointed to Zenith and permission to use the Argos swing arm calibration unit.

**Procedure**
- AO optimization procedure comes here 

**Templates**

**Success criteria**
- SOUL AO system is working in tandem with the SHARK-NIR system.
- Acceptable improvement of the on-axis PSF (Argos Swing arm calibration light source) while SOUL AO is closed with known disturbances. 
- If necessary, get a new and improved daytime telescope model for SHARK-NIR.

**Notes**

**LBTO support**
- Authorize SHARK-NIR on the SX side.
- Authorize mode to use the Argos Swing Arm. RR will be required on the SX side, if not the Argos swing arm.
- AO support.
