== [[span(style=color: green, **SDC6	Detector persistence** )]] ==

- **Phase**		:	1  
- **Status**		: 	[[span(style=color: green, **COMPLETE** )]]  
- **Category**	: 	Daytime calibration (C3)
- **Recurrence**	: 	once every 1-3 months starting from commissioning.
- **Duration**	: 	20 minutes (this duration is valid only during regular operations, i.e., after commissioning)

**Description**
- Monitor persistence after saturation. 

**Prerequisites**
- Instrument and dome closed. No lights inside the dome.

**Procedure**
- Record a background exposure, then one highly saturated exposure; then a long series of exposures with source off. 
- CI B_H point source.

**Templates** 
- SHARKNIR_ci_mon_DetectorPersistence (not released)

**Success criteria**
- Accuracy of photometry 10%.

**Notes**
- Same as activity 9.3 in AD4
