Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, Since the most fundamental limit to detect very distant objects is the source confusion, the estimation of the source confusion limit of SPICA is very important to decide the observational strategy. We estimated the confusion limit of SPICA from 5 to 200 μm. For the mid- and far-IR (MIR and FIR) galaxy counts, we used an updated version of the empirical galaxy number count model of Takeuchi et al. (2001). At 5 μm, we used a semi-analytic galaxy evolution model “ νGC” to construct the galaxy number counts. Based on his, confusion limits for SPICA were estimated by the analytic formulation that can deal with angular clustering of the galaxies (Takeuchi & Ishii 2004)., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027036, レポート番号: JAXA-SP-17-010E}, pages = {157--159}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Estimation of the Confusion Limit for SPICA}, volume = {JAXA-SP-17-010E}, year = {2018} }
