- **Phase**		:	3  
- **Status**		: 	[[span(style=color: green, **COMPLETE** )]]	 	 
- **Category**	: 	Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6)
- **Recurrence**	: 	before every observing target (CI, LSS), starting from commissioning.
- **Duration**	: 	2 hours

**Description**
- Alignment of the internal pupil image with apodizer (at PP1) or Lyot stop (at PP2) in the coronagraphic mode 

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

**Procedure**
- The position of the first tip-tilt mirror (IN_TT) is optimized in order to have the first pupil image centered with the apodizer/Lyot stop. This is obtained by comparing the pupil image, formed on the SCICAM, with the image of the apodizer, received on the SCICAM using the calibration fiber as a source. 

**Templates**
- SHARKNIR_gen_tec_PupilApoAlignment
- SHARKNIR_gen_tec_PupilLyotAlignment

**Success criteria**
- Expected accuracy: 0.25% of pupil image diameter ~17arcsec of the TTM ~1.5pixel SCICAM ~30μm at the level of the SCICAM.
