== SDC7 Spectral resolution == 
•	**Phase**		:	Any  
•	**Status**		: 	Draft	 
•	**Category**		: 	Daytime calibration (C3)
•	**Recurrence**	: 	once every month starting from commissioning.
•	**Duration**		: 	10 minutes
**Description**
•	Measure the spectral resolution for the LSS observing mode.
**Prerequisites**
•	Bad pixel map, Background frames 
**Procedure**
•	This calibration is performed illuminating the slit with the instrument spectral calibration lamps with known characteristics (5 emission lines). A background with lamps switched off is required.
**Success criteria**
•	Accuracy of MRS: 0.5nm at 1.2 micron, LRS: 2 nm at 1.2 micron. 
**Notes**
•	Same as activity 9.4 in AD4
