Intensity-weighted peak velocity (moment 1) maps of molecular lines with extended emission in ISOSS J23053+5953. The moment 1 map is presented in color scale (using a threshold of S∕N ≥ 3 of the line integrated intensity). The NOEMA 1.3 mm continuum data are shown in pink contours. The dotted pink contour marks the − 5σ_cont level. Solid pink contour levels are 5, 10, 20, 40, and 80σ_cont. The synthesized beam of the continuum data is shown in the bottom left corner. The synthesized beam of the spectral line data is similar.
