v3 v4 6 6 Z 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. 7 7 [[BR]] 8 8 https://clover.pas.rochester.edu/trac/astrobear/wiki/zcooling# 9 9 == Zcooling.tab == 10 10 Understanding the format of this table is crucial to interpolating correctly. There are a few properties that this table must have: … … 16 16 3.) 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). 17 17 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^2where nH is the number density of hydrogen.18 Also, it is important to note that the cooling rate has units of erg * cm^-3^ * nH^-2^.
