v12 v13 1 == P3.12 Star center Fourier mode images == 2 • **Phase** : 3 3 • **Status** : Draft 4 • **Category** : Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6) 5 • **Recurrence** : on every target, starting from commissioning. 6 • **Duration** : 2 days 1 == P2.7 Star center Fourier mode images == 2 3 - **Phase** : 2 4 - **Status** : Draft 5 - **Category** : Daytime testing (functionality and operability) (C3) + Daytime calibration (C4) 6 - **Recurrence** : once after instrument installation at telescope platform 7 - **Duration** : 2 days 8 7 9 **Description** 8 • 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 - 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. 11 9 12 **Prerequisites** 10 • Authorize SHARK-NIR on the SX side. 11 • Atmospheric conditions: AO working conditions. 12 • Bad pixel map, Dark 13 - Authorize SHARK-NIR on the SX side. 14 - Atmospheric conditions: AO working conditions. 15 - Bad pixel map, Dark 16 13 17 **Procedure** 14 • DM produce a pattern offset with four spots symmetric with respect to the star + AO closed-loop + coronagraph 15 • 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. 16 • 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. 18 - DM produce a pattern offset with four spots symmetric with respect to the star + AO closed-loop + coronagraph 19 - 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. 20 - 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. 21 22 **Templates** 23 17 24 **Success criteria** 18 • Accuracy of 3 mas (goal 1 mas) 25 - Accuracy of 3 mas (goal 1 mas) 26 19 27 **Notes** 20 • Same as activity 7.8 in AD4 28 - Same as activity 7.8 in AD4 29 21 30 **LBTO support** 22 • AO support 23 **Associated SHARK-NIR personnel** 31 - AO support 24 32 25 33 **Date performed and by whom** 26 27 ** Comments**
