Query: Observational Constraints of Modified Chaplygin Gas in RS II Brane   FRW universe in RS II braneworld model filled with a combination of dark
matter and dark energy in the form of modified Chaplygin gas (MCG) is
considered. It is known that the equation of state (EoS) for MCG is a
three-variable equation determined by $A$, $\alpha$ and $B$. The permitted
values of these parameters are determined by the recent astrophysical and
cosmological observational data. Here we present the Hubble parameter in terms
of the observable parameters $\Omega_{m0}$, $\Omega_{x0}$, $H_{0}$, redshift
$z$ and other parameters like $A$, $B$, $C$ and $\alpha$. From Stern data set
(12 points), we have obtained the bounds of the arbitrary parameters by
minimizing the $\chi^{2}$ test. The best-fit values of the parameters are
obtained by 66%, 90% and 99% confidence levels. Next due to joint analysis with
BAO and CMB observations, we have also obtained the bounds of the parameters
($B,C$) by fixing some other parameters $\alpha$ and $A$. The best fit value of
distance modulus $\mu(z)$ is obtained for the MCG model in RS II brane, and it
is concluded that our model is perfectly consistent with the union2 sample
data.
