Comparison of the integrated intensity of SO 6₅−5₄ between −81.8 and −0.8 km s⁻¹ with different imaging choices. The left and middle-left columns show results with only the NOEMA visibilities while the middle-right and right columns show the results with the 30 m short-spacing information included. The maps in the left and middle-right columns were imaged with the Clark algorithm while those in the middle-left and right columns were imaged with the SDI algorithm. The top row was imaged with uniform weighting, the middle row using a GILDAS-robust parameter of 3 to give an intermediate beam-size, while the bottom row using natural weighting. The intensity scale is chosen to show the extended emission, with the peak intensity for the hot core being between ~240 and ~790 K km s⁻¹, depending on the method.
