C¹⁷O velocity-weighted integrated intensity maps toward IRS3B and IRS3A over a selected range of velocities (1.27 ﹩\to ﹩ 7.65 km s⁻¹) The C¹⁷O emission appears well ordered across the semimajor axis. The contours denote the 0.5 km s⁻¹ velocity offsets from system velocity of 4.8 km s⁻¹. The yellow markers indicate the three continuum sources. The black lines indicate the position angle of the minor disk estimates as given by the pdspy fitting routine in Table 4, of ﹩90+{26.7}_{-2.9}^{+1.8}﹩°. The C¹⁷O synthesized beam (0.″21 × 0.″13) is the bottom rightmost ellipse.
