Observation: Ellipticity and position angle (PA) of the fitted elliptical isophotes as a function of their semimajor axis (SMA) (left) and the image of the galaxy in the NIRCam F444W filter (right). The masked regions excluded from the isophote fitting analysis are shown with dimmer colors while the isophotes, and their respective properties, for which formal convergence was not reached are plotted with semi-transparent colors. The observed bar radius is constrained using the peak of the ellipticity profile, located at ≈ 0 . $ \overset{\prime \prime }{.} $5 from the center of the galaxy, with a corresponding PA of PAbar≈ -10° for the bar. The disk PA and inclination derived using the outer elliptical isophote (PA ≈ -23° and i ≈ 49° neglecting the thickness of the disk) are in excellent agreement with the values constrained using the kinematics and priors described in Sect. 2.3.
