Observed lines of CH2OHCHO toward the protostar NGC 1333 IRAS2A (in black). The best-fit model for CH2OHCHO (see Table 2) is shown as red solid lines. The line in the third upper panel is blended with an unidentified species. The contribution of the CH3OCHO lines is indicated with green lines, and the model including both CH2OHCHO and CH3OCHO can be seen as red dotted lines.
