Overview picture of the velocity gradients (top panel), velocity linewidths (middle panel) and mass accretion rates (bottom panel) along all filaments and subfilaments (indicated by roman numbers) in Sgr B2(N), see Sects. 3.1 and 3.2. Additional velocity components in filament F06 are marked as 6a and 6b. The gray, green, blue, and orange symbols correspond to the molecules CH₃OCHO, CH₃OCH₃, CH₃OH and ¹³CH₃OH, respectively.
