•	**Phase**		:	1  
•	**Status**		: 	Draft	 
•	**Category**		: 	Installation, integration, verification (C1)				
•	**Recurrence**	: 	once
•	**Duration**		: 	6 hour(s)
**Description**
•	Calibration of the SHARK-NIR science detector: Gain, bad pixels, read noise, linearity, dark current, flat field, cross-talk, persistence, pattern noise.
**Prerequisites**
•	SHARK-NIR connected to LBT network.
•	Electronics cabinets on.
•	The cryostat should be running and cooled down.
•	Internal alignment of the SHARK-NIR is verified.
**Procedure**
•	check linearity, create bad pixel mask, bias calibration, master dark, and then perform the following daytime calibration procedures below.

**Success criteria**
•	linearity as expected
•	bad pixels mask created
•	bias and flat took
**Notes**
•	Save all the intermediate images for Dino to check the SHARK-NIR Data Reduction pipeline.
