Example case Sgr B2(N). Top-left. Continuum emission map as determined with the c-SCM method of STATCONT. The synthesized beam is 0.̋4. Top-right: continuum emission map determined after searching and selecting line-free channels. Middle-left: noise map obtained with c-SCM. Middle-right: ratio of the c-SCM to classical-approach continuum maps. Bottom panels: continuum-subtracted spectra using the c-SCM value towards two selected positions A and B, shown in the top-left panel. The channels used for the continuum determination after clipping and converging are depicted in red. The c-SCM continuum emission level subtracted to the original spectra, together with its uncertainty, are listed in the upper part of each panel. See more details of these data in Sánchez-Monge et al. (2017).
