Notes. The coordinates mark the position from which the spectra were extracted. All column densities are derived for the reported Tex and assuming the source size is equal to the size of the beam (i.e., beam dilution = 1). The column density of CH3OH is derived from the 
and 13CH3OH isotopologues when these are detected. If neither isotopologue is detected but CH3OH is, a range in column densities is presented where the lower limit it the column density derived from CH3OH and the upper limit is scaled from the upper limit on 13CH3OH. If CH3OH itself is also not detected, an upper limit is directly derived from its spectrum.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
