Fig. B.1

Reaction rate coefficients following Equation 14 for all neutral molecules in the database. The boxes show the minimum and maximum coefficients in the column density range 10²⁰ cm⁻² cm^-2, and plus signs show the mean. The cyan boxes denote molecules using the MP2 calculations, and the red boxes denote calculations from Heathcote & Vallance (2018).

This figure is made of several images, please see below:
