== P2.7 Checking pointing offset between SHARK-NIR and SOUL-AO== 
•	**Phase**		:	2  
•	**Status**		: 	Draft	 
•	**Category**		: 	Daytime testing (functionality and operability) (C2)
•	**Recurrence**	: 	once at commissioning
•	**Duration**		: 	3 days
**Description**
•	Test to check if there is a considerable pointing offset between the SHARK-NIR (SCICAM/TECCAM) and SOUL-AO as a function of the elevation of the telescope
**Prerequisites**
•	If relevant, estimate and remove the NCPA using the phase-diversity method.
•	RR mounted on SX side.
**Procedure**
•	Need to define the procedure?

**Success criteria**
•	Estimate the pointing offset and conclude if it is acceptable or not. If not acceptable, take proper actions to overcome this issue.
**Notes**

**LBTO support**
* Authorize SHARK-NIR on the SX side.
* RR mounted on the SX side.
* Support from LBT SW Team, LBTI/Arcetri team to run SOUL AO

**Associated SHARK-NIR personnel**

MB: Given the adjustment of SOULD LBT wrt to elevation should already have been done previsouly, I'd say it would be best to have also a look up table at least for TT where dichroic and in-TT are adjusted to compensate flexures [okay. in that case, we may need more time. lets discuss.]

LM: this topic needs discussion, but in principle, this can be done together with the NCPA tests (2.6). Basically, when changing the elevation of the telescope, re-acquire the on-axis source with SOUL and record how much the Pyramid WFS moved from one elevation to another one in order to re-center it on the source (maybe this already exists). After SOUL acquired the on-axis source, look for it on the TECCAM and use our internal mirrors (IN-TT and DM) to re-center the PSF and pupil on the hot pixels. If big adjustments of our mirror positions are required, we can build the look-up table (--> define "big"). Flexures of the RR or ARGOS source affect the result.
