Example of integrated intensity (moment 0; left panels), mean line-of-sight velocity (moment 1; middle-left panels), velocity dispersion (moment 2; middle-right) maps and spectra (right panels) of 2 detections in the CO-ARC sample. The moments maps for all the 17 detections are shown in the Appendix in Fig. A.1. The synthesized beam is shown as a blue ellipse in the bottom-left corner of each moment 0 map. The bar to the top of each moment map shows the color scales (in Jy beam⁻¹ km s⁻¹ and km s⁻¹ for moment 0 and moment 1/2 maps, respectively). East is to the left and north to the top. The observed CO transition is indicated in the top-right corner of each spectral profile. The aperture within which the illustrated spectra have been extracted are overlain in green in each moment 0 maps.
