This stores the variables used to calculate the parameters for h2, no, vr, etc. in the cloud. There are seven lines in the file, one for each parameter (in order they are: vr, vt, vz, h2, tk, no, tu). Each parameter is described by three variables, say $a$, $b$ & $c$. These are used to calculate the parameter values at the disk and cylinder intersections using:

$$paramvalue=\frac{a}{1+\left(\frac{b}{r_c}\right)^2+ \left(\frac{c}{r_d}\right)^2}$$

where $r_{c}$ and $r_d$ are, respectively, the cylinder and disk co-ordinates.
