v7 v8 1 1 == P3.2 Telescope control – telescope mode, offset, and focal plane geometry estimation== 2 • **Phase** : 3 3 • **Status** : Draft 4 • **Category** : Nighttime testing (functionality and operability) (C5) 5 • **Recurrence** : once at commissioning 6 • **Duration** : 2 hours 2 3 - **Phase** : 3 4 - **Status** : Draft 5 - **Category** : Nighttime testing (functionality and operability) (C5) 6 - **Recurrence** : once at commissioning 7 - **Duration** : 2 hours 8 7 9 **Description** 8 • For the correct telescope mode for SHARK-NIR, find the offset direction & magnitude (for the field-stabilized mode), verify the proper image orientation, pixel scale, field of view, and distortion at the SCICAM. Note that this may be performed with and without AO running. 10 - For the correct telescope mode for SHARK-NIR, find the offset direction & magnitude (for the field-stabilized mode), verify the proper image orientation, pixel scale, field of view, and distortion at the SCICAM. Note that this may be performed with and without AO running. 11 9 12 **Prerequisites** 10 • Atmospheric conditions: should be able to see bright stars in the sky (preferably close to zenith?). 11 • Authorize SHARK-NIR on the SX side. 12 • Suitable binary or astrometric targets. 13 • AO running for part of the test. 13 - Atmospheric conditions: should be able to see bright stars in the sky (preferably close to zenith?). 14 - Authorize SHARK-NIR on the SX side. 15 - Suitable binary or astrometric targets. 16 - AO is running for part of the test. 17 14 18 **Procedure** 15 1. **Procedure**for image orientation19 1. Procedure for image orientation 16 20 - Select a filter 17 21 - Place the de-rotator in the nominal "zero" position. 18 22 - Issue a preset to move to a bright star (but not too bright to saturate) 19 23 - Center the star in the science channel 20 - Issue a pure elevation offset to the TCS of ca. 5 ”and verify expected motion direction on the SCICAM24 - Issue a pure elevation offset to the TCS of ca. 5" and verify expected motion direction on the SCICAM 21 25 - Return to the on-axis position and repeat with a pure azimuth motion. 22 26 - Issue a preset to move to a suitable astrometric binary (typically 5-8 arcsec separation) and center one star in the science channel. 23 27 - Based on the published coordinates of the binary, issue the appropriate offset to center the other star. 24 2. **Procedure**for pixel scale/ plate scale28 2. Procedure for pixel scale/ plate scale 25 29 - Select a filter 26 30 - Issue a preset to move to a suitable astrometric binary to measure pixel scale (typically 5-8 arcsec separation) … … 29 33 - Use the difference image (optionally flat-fielded) to verify the expected pixel scale. This gives two measures. 30 34 - Repeat this for other filters. 35 36 **Templates** 37 31 38 **Success criteria** 32 • The image orientation is as expected. The pixel scale and field of view of the SCICAM are as expected. 39 - The image orientation is as expected. The pixel scale and field of view of the SCICAM are as expected. 40 33 41 **Notes** 34 42 35 43 **LBTO support** 36 44 37 **Associated SHARK-NIR personnel**38 39 45 **Date performed and by whom**
