    66Z cooling is an energy loss due to forbidden line emission.  The routines use Pat Hartigan's cooling table Zcooling.tab.  The table does not include recombination or permitted line emission.

    1010Understanding the format of this table is crucial to interpolating correctly.  There are a few properties that this table must have:
     
    16163.) The very first line of the table needs to have nDensities, nTemps, nXs.  As an example, the first line might read: 40 30 21.  This means there are 40 different values for log(ne), 30 for T, and 21 for log(X).  Thus, there are a total of 25,200 different values for the cooling rate (40*30*21 = 25,200).

    18 Also, it is important to note that the cooling rate has units of erg * cm^-3 * nH^-2.  So before the rate can be added to the change in energy, dqdt(iE), it must be multiplied by nH^2 where nH is the number density of hydrogen.
