== P3.7	Checking field-stabilized mode/bearing rotation service == 
 
- **Phase**		:	3  
- **Status**		: 	Draft	 
- **Category**	: 	Nighttime testing (functionality and operability) (C5)
- **Recurrence**	: 	once at commissioning
- **Duration**	: 	2 hours

**Description**
- The field stabilized mode, or in other words, the working of the bearing tracking service, will be tested.

**Prerequisites**
- Atmospheric conditions: AO working conditions.
- Authorize SHARK-NIR on the SX side.
- Targets (star cluster) near zenith and horizon (say airmass of 2).

**Procedure**
- Select the target near airmass 2. There should be stars spread across the entire SCICAM, preferably close to the edges as well.
- Start the bearing tracking services (field-stabilized mode). 
- Take short-exposure images for a duration of ##minutes.
- Check the positions of these stars.
- Repeat the same for the target close to the zenith. 
- Repeat the same steps for a target where the rotation of the bearing is in the opposite direction.

**Templates**

**Success criteria**
- The bearing tracking service works well, and the field is stabilized within the precision needed.
