Temperature (temperature)

Define temperature, in units of $10^4 K$. If the parameter         niter is set to 0 then the temperature is fixed at this value. Otherwise the value is used as a first guess in calculating the thermal equilibrium value. If the pressure is specified it is also used to calculate an initial guess at the gas density, $n=P/(kT)$, which is then used to calculate $\Delta R_{max}=N/n$. Default value is 1.
