Supporting Material for Evolution of Chemistry in the envelope of HOt corinoS (ECHOS) III. Sulphur chemistry in the Class 0 objects HH 212 and NGC 1333 IRAS 4A

Supporting Material for "Evolution of Chemistry in the envelope of HOt corinoS (ECHOS) III. Sulphur chemistry in the Class 0 objects HH 212 and NGC 1333 IRAS 4A". The file supporting-material.pdf includes the line parameters of molecules detected in HH 212 and IRAS 4A, the range of column densities and H$_2$ densities used in the grid of RADEX, and the plot of the spectra of each of the detected lines. The archive ascii_files.zip contains the spectra and fits of each detected line in ascii format: first column corresponds to the velocity of local standard rest of each object, second column is expressed in terms of main beam brightness temperature, and third through fifth columns are the Gaussian fittings.
