•	**Phase**		:	3  
•	**Status**		: 	Draft	 
•	**Category**		: 	Nighttime testing (functionality and operability) (C4)
•	**Recurrence**	: 	once at commissioning
•	**Duration**		: 	50 minutes
**Description**
•	Limiting magnitude is verified for each scientific filter, with the LBTI AO running.
**Prerequisites**
•	Atmospheric conditions: photometric.
•	Authorize SHARK-NIR on the SX side.
•	Photometric stars as targets for every filter.
•	AO working.
**Procedure**
•	Take unsaturated images of the photometric star for every science filter.
•	Estimate the instrument throughput for every filter.
**Success criteria**
