V.B.4.e.3. Spectral Comparisons
Figure V.B.4.e.3-1 shows relatively isolated lines of intermediate strength, whose shapes observed in the ALMA spectrum are characteristic of the lineshapes of methyl cyanide, ethyl cyanide, and vinyl cyanide. The lines of the latter two show clear shoulders on their low frequency sides, which are due to the kinematics of the region probed by the ALMA beam. These lineshape are convolved with the CES to produce the simulations that are compared with the ALMA results below.
Figure V.B.4.e.3-1. Relatively isolated lines of intermediate strength that were used for the ALMA lineshapes of methyl cyanide, ethyl cyanide, and vinyl cyanide (top to bottom). The solid black traces are the ALMA data and the dashedcolored traces are the convolution of the simulated lineshape with the CES.
