| 25 | • After pre-set and acquisition of the target we will run on flux calibration template with the star off-centered from the coronagraph (short templete - few minutes). To this a centering |
| 26 | observation follows with the Fourier mode on the DM allowing the creation of four satellite spots (around 5% of the target brightness). Also this template is short. |
| 27 | We then perform the scientific coronagraphic observation using pupil stabilized observing mode. This observation should be taken during the passage of the star to the meridian to maximize |
| 28 | the rotation of the FOV and allow to implement ADI. This part should be long at least 1:20-1:30 hours. The observation is closed running again centering and flux calibration with the same |
| 29 | modalities adopeted at the beginning of the observations. |
