  The broad Iron line in MCG-6-30-15 is fitted to the Comptonization model
where line broadening occurs due to Compton down-scattering in a highly ionized
optically thick cloud. These results are compared to the disk line model where
the broadening is due to Gravitational/Doppler effects in the vicinity of a
black hole. We find that both models fit the data well and it is not possible
to differentiate between them by fitting only the ASCA data. The best fit
temperature and optical depth of the cloud are found to be kT = 0.54 keV and
$\tau = 4.0$ from the Comptonization model. This model further suggests that
while the temperature can be assumed to be constant, the optical depth varies
during the observation period. We emphasis an earlier conclusion that
simultaneous broad band data ($3 - 50$ keV) can rule out (or confirm) the
Comptonization model.
