Column densities of ten complex organic molecules normalized to the column density of methanol as a function of disk size (FWHM), disk flux density, and ratio of disk to envelope flux densities taken from Maury et al. (2019). The column densities of some molecules were multiplied by a scaling factor as indicated on the right. Filled and open squares represent robust and tentative detections, respectively, while open triangles show upper limits. Arrows indicate upper limits along the horizontal axis. GA stands for glycolaldehyde, CH2 (OH)CHO.
