Fig. A.6


Luminosity ratio of HCO+ to CO for each molecular complex. We show one plot for each region. The x-labels indicate the number of each velocity componet as defined by Gaussian fit (see Table 3). The main component is indicated by an asterisk. In blue we show the luminosity ratio for disk clouds and in red we show the luminosity ratio for Galactic center clouds. Each region is located in the HCO+ integrated intensity map with an arrow. The highest intensities ratio belong to the Galactic center cloud (for example in Sgr B region).

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.
