Contours denoting β_app = 0.32 and 1.60 as a function of β and θ_view, represented by solid black lines (left). The contours corresponding to the apparent speed values deviated by 1σ errors are depicted by dotted black lines. The blue hashed region indicates the inferred range of jet viewing angles, θ_view = 18 − 30°, based on previous studies employing SED modeling (Abdo et al. 2009; Aleksić et al. 2014; Tavecchio & Ghisellini 2014). Similarly, the red hashed region represents the range of θ_view = 30 − 65° inferred from observations of the counterjet (Walker et al. 1994; Asada et al. 2006; Fujita & Nagai 2017). The green solid line emphasizes a viewing angle of 6°, which yielded a satisfactory fit to the observed SED but was considered unreliable due to its significant deviation from the viewing angles determined through radio observations (Tavecchio & Ghisellini 2014). Contours corresponding to various values of the Doppler factor δ are presented as functions of β_app and θ_view (right). The vertical dashed lines indicate the observed apparent speeds of the knot, β_app = 0.32 and 1.60.
