Notes. Optical depth values calculated from RADEX using the LVG method for all three CO transitions across all regions defined based on the outflow. The second column indicates the different FWHM line widths (ΔvFWHM) applied to different regions. The third column lists the H2 number density values used for each region, with two different densities applied per region. For each region, the second row (corresponding to n H 2 = 10 6 cm − 3 $ n_{\mathrm {H_2}} = 10^6\,\rm {cm^{-3}} $) follows the same region code and line width as the row above. The last three columns display the optical depth values for the CO transitions specified in the column headers. Optical depth values ≥1 are marked by the “†” symbol.
