COEFDATA.*** (2)

This file contains the collision coefficients for a particular molecule. The first line contains 2 numbers: the first is the number of temperatures for which the collision rates have been calculated and the second is the number of transitions for which the collision rates have been calculated. The second line lists the temperatures (K) at which the collision rates have been calculated - each temperature refers to the column below it. Note that the collision rates should be with molecular hydrogen - care should be taken here as some published listings of collision rates are with Helium and need to be converted.

The rest of the file tabulates the rates. Each column represents one temperature. If the first line said there were i transitions then the rows, in order, represent the collision rates for transitions 0 $\rightarrow$0, 1 $\rightarrow$0, 2 $\rightarrow$0, ... ,i $\rightarrow$0, 0 $\rightarrow$1, 1 $\rightarrow$1, 2 $\rightarrow$1, ... , i $\rightarrow$1, 0 $\rightarrow$2, ... , i $\rightarrow$i.
