  A detailed multi-epoch study of the broadband spectral behaviour of the very
high energy (VHE) source, 1ES\,1011+496, provides us with valuable information
regarding the underlying particle distribution. Simultaneous observations of
the source at optical/ UV/ X-ray/ $\gamma$-ray during three different epochs,
as obtained from Swift-UVOT/ Swift-XRT/ Fermi-LAT, are supplemented with the
information available from the VHE telescope array, HAGAR. The longterm flux
variability at the Fermi-LAT energies is clearly found to be lognormal. It is
seen that the broadband spectral energy distribution (SED) of 1ES\,1011+496 can
be successfully reproduced by synchrotron and synchrotron self Compton emission
models. Notably, the observed curvature in the photon spectrum at X-ray
energies demands a smooth transition of the underlying particle distribution
from a simple power law to a power law with an exponential cutoff or a smooth
broken power law distribution, which may possibly arise when the escape of the
particles from the main emission region is energy dependent. Specifically, if
the particle escape rate is related to its energy as $E^{0.5}$ then the
observed photon spectrum is consistent with the ones observed during the
various epochs.
