v21 v22 1 == P2.8 Star center Fourier mode images==1 == P2.8 Verification of the mask centering algorithm and final contrast with SOUL-AO and turbulence at ASM== 2 2 3 3 - **Phase** : 2 4 4 - **Status** : Draft 5 - **Category** : Daytime testing (functionality and operability) (C3) + Daytime calibration (C4)6 - **Recurrence** : once a fter instrument installation at telescope platform7 - **Duration** : 0.5 day5 - **Category** : Daytime testing (functionality and operability) (C3) 6 - **Recurrence** : once at commissioning 7 - **Duration** : 3 days 8 8 9 9 **Description** 10 - This calibration is performed to calibrate the target star center with respect to the detector in order to provide a reference input for frame derotation and quadrant combination.10 - Verify the efficiency of the mask-centering algorithm and the final contrast with SOUL-AO and artificial turbulence intruded at the ASM. 11 11 12 12 **Prerequisites** 13 - Authorize SHARK-NIR on the SX side. 14 - Atmospheric conditions: AO working conditions. 15 - Bad pixel map, Dark 13 - RR is mounted on the SX side. 16 14 17 15 **Procedure** 18 - TBW+TBC 19 - DM (ASM/ALPAO-DM?) produces a pattern offset with four spots symmetric with respect to the star + AO closed-loop + coronagraph 20 - The required specifications of the corresponding image are a grid of at least 2x2 regularly spaced focal plane image peaks within 5 and 15 lambda/D with FWHM < 45 mas and separation precision < 6 mas. 21 - DM offset applied on target acquisition to produce a waffle image. Find the center of the four first-order diffraction peaks (cross geometry) to deduce the pixel corresponding to the center field. 16 - TBW 22 17 23 18 **Templates** 24 - SHARKNIR_gen_cal_StarCenter (not released)25 19 26 20 **Success criteria** 27 - Accuracy of 3 mas (goal 1 mas)21 - Final contrast produced for various seeing conditions matches the simulations. 28 22 29 23 **Notes** 30 - Same as activity 7.8 in AD431 24 32 25 **LBTO support** 26 - Authorize SHARK-NIR on the SX side. 27 - RR is mounted on the SX side. 33 28 - AO support 34 29
