This mission focuses on the Galactic center region, obscured by interstellar dust in optical wavelengths. JASMINE’s observation strategy differs from other missions and must be verified via dedicated simulations. To verify the mission concept, we designed a simplified simulation, the JASMINE mini survey, covering three years with 100 orbits. As a simple case, the data obtained in a single satellite orbit are analyzed simultaneously (Plate Analysis). The observation model was made differentiable and implemented as a probabilistic model to make the best use of Stochastic Variational Inference. Model parameters converged to a certain solution, while the observation model contained more than 30,000 parameters. The estimated coordinates well represented the stellar motions expected from the ground truth. A typical positional error was estimated to be about 70 µas, consistent with the measurement error and the number of measurements. The present results validate parts of JASMINE’s mission concepts, leading to significant advancements in understanding the Galactic center. date: 2024-07-25 date_type: published publisher: SPIE official_url: http://dx.doi.org/10.1117/12.3017291 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2310846 doi: 10.1117/12.3017291 isbn_13: 9781510675254 lyricists_name: Kawata, Daisuke lyricists_id: DKAWA39 actors_name: Kawata, Daisuke actors_id: DKAWA39 actors_role: owner full_text_status: public pres_type: paper publication: Proceedings of SPIE - The International Society for Optical Engineering volume: 13101 place_of_pub: Bellingham, WA, USA pagerange: 131011R event_title: SPIE Astronomical Telescopes and Instrumentation 2024 event_location: Yokohama, Japan event_dates: 16 Jun 2024 - 22 Jun 2024 issn: 0277-786X book_title: Software and Cyberinfrastructure for Astronomy VIII editors_name: Ibsen, Jorge editors_name: Chiozzi, Gianluca citation: Ohsawa, Ryou; Kawata, Daisuke; Kamizuka, Takafumi; Yamada, Yoshiyuki; Löffler, Wolfgang; Biermann, Michael; (2024) Concept verification of the JASMINE astrometric plate analysis.
