Comparison of moment-zero maps for detected molecular lines in IRAS 06530−0213. Crosses mark the phase center, and the white ellipse in the bottom-left corner denotes the synthesized beam (0﹩\mathop{.}\limits^{{\unicode{x02033}}}﹩72 × 0﹩\mathop{.}\limits^{{\unicode{x02033}}}﹩41). The map of SiC₂ is produced by stacking the two maps shown in Figure 8.
