Notes. To avoid redundancy, the percentages of ice column densities of H2O in CH3 OH, CO in CH3 OH, and CH3 OH in CO w.r.t. the total H2O, CO, and CH3OH ice column densities are not tabulated. They are equal to 100 minus the value reported in the corresponding column (e.g. 10.3 cm−2 for H2O in CH3 OH towards SVS 4−2). See Sect. 3.1 and Appendix A for a more detailed description of the determination of ice column densities.
