     2
     3- **Phase**             :       3 
     4- **Status**            :       Draft   
     5- **Category**  :       Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6)
     6- **Recurrence**        :       once at commissioning and then for each LSS observation.
     7- **Duration**  :       2 hours
     8
     9**Description**
     10- Absolute flux calibration per spectral resolution element.
     11
     12**Prerequisites**
     13- Authorize SHARK-NIR on the SX side.
     14- Atmospheric conditions: AO working conditions.
     15- Bad pixel map, Background or Dark, Flat-field, wavelength calibration.
     16
     17**Procedure**
     18- Preset to the targeted star.
     19- Eventually, center the star behind the slit occulter.
     20- Apply an offset using the internal DM to move the star outside the occulting mask (but still into the slit).
     21- Take the spectrum of the star.
     22
     23**Templates**
     24- SHARKNIR_lss_cal_FluxCalibration
     25
     26**Success criteria**
     27- Better than 10% for absolute flux calibration.
     28
     29**Notes**
     30- Same as activity 7.4 in AD4
     31
     32**LBTO support**
     33- AO support
