Query: Observational Constraints on the Model Parameters of a Class of Emergent
  Universe   A class of Emergent Universe (EU) model is studied in the light of recent
observational data. Significant constraints on model parameters are obtained
from the observational data. Density parameter for a class of model is
evaluated. Some of the models are in favour of the recent observations. Some
models have been found which are not interesting yielding unrealistic present
day value of the density parameter.
