Plot of the intensity of pixels in the methyl formate maps versus the intensity of the same pixels in the dimethyl ether (top left), ethanol (top right), formic acid (bottom left) and methyl formate (bottom right) maps. Care has been taken to use transitions with similar Eu energies. The methyl formate (Eu = 305 K) at 223.534 GHz is compared to the dimethyl ether transition (Eu = 330 K) at 223.41 GHz and to the ethanol transition (Eu = 346 K) at at 223.629 GHz. The methyl formate transition (Eu = 50 K) at 223.500 GHz is compared to the formic acid transition (Eu = 72 K) at 223.915 GHz and to the methyl formate transition (Eu = 50 K) at 223.465 GHz. Dimethyl ether shows clearly the highest spatial correlation with methyl formate.
