SMA images of the observed FUors, EXors, and FUor-like objects. Images are taken at the mean frequency of 224–225 GHz (1.33 mm) if not specifically annotated. The synthesized beam is shown in the bottom left corner of each panel. Color bars are in units of mJy beam⁻¹. Contours are in steps of 3σ (cf. Table D.1) if not specifically mentioned. Contours of L1551 IRS 5 are 6 mJy beam⁻¹ (2σ) × [−3, 3, 6, 12, 24, 48]. Contours of Haro 5a/6a IRS are 2.4 mJy beam⁻¹ (1σ) × [−3, 3, 6, 12, 24, 48]. Contours of V883 Ori are 7.6 mJy beam⁻¹ (1σ) × [−3, 3, 6, 12, 24, 48]. Contours of V2775 Ori are 1.9 mJy beam⁻¹ (1σ) × [−3, 3, 6, 12, 24]. Contours of V1647 Ori are 0.66 mJy beam⁻¹ (1σ) × [−3, 3, 6, 12, 24, 48, 96]. Image of NGC 2071 MM3 is presented with a θ_maj × θ_min = 5. ′′ 8 × 3. ′′ 6 (PA = 43°) synthesized beam to better present its extended envelope; contours are 0.66 mJy beam⁻¹ (1σ) × [−3, 3, 6, 12, 24,48]. Rectangle and cross in the panel of RNO 1B/1C mark the locations of RNO 1B and 1C quoted from Quanz et al. (2007a); in the panel of SVS 13 they mark Per-emb-44 A and B (Anglada et al. 2004); in the panel of L1551 IRS 5 they mark the southern and northern binary components quoted from Lim et al. (2016); in the panel of XZ Tau A/B they mark the locations of XZ Tau A and B quoted from Forgan et al. (2004); in the panel of VY Tau A/B they mark the location of VY Tau A and B (e.g., Dodin et al. 2015); in the panel of V1118 Ori they mark V1118 Ori and its companion (Reipurth et al. 2007a,b); in the panel of FU Ori they mark the locations of FU Ori and FU Ori S (Liu et al. 2017).
