Spectral line emission towards IRAS 23033+5951. For the first (intensity-weighted peak velocity, left panels) and second-order moment maps (line width, right panels), the flux was integrated over the velocity range vLSR ± 10 km s−1, with vLSR = −53.1 km s−1, considering emission above the 5 σ threshold of each respective molecule. The black contours indicate the 5, 10, 15, 20σ continuum emission levels and increase further in steps of 20σ, where σ = 0.28 mJy beam−1. The dashed ellipses in the lower left corner of each panel show the respective synthesized beam ≈ 0.43′′ × 0.35′′ (PA 61°).
