- **Phase**		:	1  
- **Status**		: 	[[span(style=color: green, **COMPLETE** )]]  
- **Category**	: 	Daytime calibration (C3)
- **Recurrence**	: 	once every month starting from commissioning.
- **Duration**	: 	20 minutes (this duration is valid only during regular operations, i.e., after commissioning)

**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.

**Templates**
- SHARKNIR_lss_mon_SpectraResolution

**Success criteria**
- Accuracy of MRS: 0.5 nm at 1.2 um, LRS: 2 nm at 1.2 um. 

**Notes**
- Same as activity 9.4 in AD4
