Surface Reaction Rate, surface concentration.

I'm using DEFINE_SR_RATE to control the rate of deposition of a species onto a surface. Basically:
*rr = C_UDMI(c, t, SS) * k_rs * 1056 * yi / mw;
where C_UDMI(c, t, SS) is the fraction of surface available.
What exactly is passed to the function for yi ??
The manual says: "Pointer to array of mass fractions of gas species at the surface and the coverage of site species (or site fractions)" but I don't think it is the mass fraction since F_YI(f, fthread, 0) and C_YI(c, t, 0) both return the mass fraction but yi returns a number greater than those.
Here species is the species which gets deposited and species (recorded elsewhere) is the deposited species.
The reaction is simply: species -> species.
