== SNM1 Filter wheels reproducibility monitoring == 

- **Phase**		:	Any  
- **Status**		: 	Draft	 
- **Category**	: 	Daytime calibration (C3)
- **Recurrence**	: 	once every 6 months starting from commissioning.
- **Duration**	: 	20 minutes (duration mentioned here is relevant only during regular operations, i.e., after commissioning)

**Description**
- Estimate the positioning accuracy of the filter wheels. 

**Prerequisites**
- Bad pixel map, Background or Dark, Flat-field, distortion map 

**Procedure**
- For each given position of the filter, take an image in pupil imaging mode.

**Templates**
- SHARKNIR_ci_mon_LyotMaskPos (not released)
- SHARKNIR_di_mon_MaskRepeatability (not released)

**Success criteria**
- Expected accuracy of 0.1 pixels. 

**Notes**
- Same as activity 9.7 in AD4
