v14 v15 1 == P2.7 Checking pointing offset between SHARK-NIR and SOUL-AO== 2 • **Phase** : 2 3 • **Status** : Draft 4 • **Category** : Daytime testing (functionality and operability) (C3) + Daytime calibration (C4) 5 • **Recurrence** : once at commissioning 6 • **Duration** : 1 day 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 • Test to check if there is a considerable pointing offset between the SHARK-NIR (SCICAM/TECCAM) and SOUL-AO as a function of the elevation of the telescope 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 • RR mounted on SX side. 13 - Authorize SHARK-NIR on the SX side. 14 - Atmospheric conditions: AO working conditions. 15 - Bad pixel map, Dark 16 11 17 **Procedure** 12 • TBD 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** 13 23 14 24 **Success criteria** 15 • Estimate the pointing offset and conclude if it is acceptable or not. If not acceptable, take proper actions to overcome this issue. 25 - Accuracy of 3 mas (goal 1 mas) 26 16 27 **Notes** 17 * This activity will be done along with P2.6 28 - Same as activity 7.8 in AD4 29 18 30 **LBTO support** 19 * Authorize SHARK-NIR on the SX side. 20 * RR mounted on the SX side. 21 * AO support 22 23 **Associated SHARK-NIR personnel** 24 31 - AO support 25 32 26 33 **Date performed and by whom** 27 28 **Comments**
