$25^{\circ}$. If we assume a source spectrum similar to that of the Crab Nebula (i.e d$\Phi$/dE = 2.79$\times$ 10$^{-11}$ E$^{-2.59}$ cm$^{-2}$ s$^{-1}$ TeV$^{-1}$ ; as measured by the $HEGRA$ group [@Crab]) and also found to match very well with the spectrum obtained from the $TACTIC$ [@Tact07], the above 99$\%$ limit translates to an integral flux upper limit of 0.26 CU. Referring back to the upper limit, if we assume a steeper spectrum (i.e d$\Phi$/dE $\propto$ E$^{-3.0}$) for 1ES1218+304, similar to the one observed by $MAGIC$ and $VERITAS$ telescopes [@Alber06; @Accia09], the above upper limit on the integral flux corresponds to about 0.23 CU above a threshold energy of 1.1 TeV. The differential flux upper limit at 99$\%$ confidence level is found to be 6.2$\times$ 10$^{-12}$ photons cm$^{-2}$ s$^{-1}$ TeV$^{-1}$.

Analysis of multi-wavelength data
=================================

The MWL data for 1ES 1218+304 were collected in optical and UV by *Swift*-UVOT, in X-rays by *Swift*-XRT, and in HE $\gamma$–rays by *Fermi*-LAT during March 1, 2013 to April 15, 2013 (MJD 56352–56397). The details of observation and data reduction for these instruments are described below.

*Fermi*-LAT data
----------------

The *Fermi*-LAT is a pair conversion $\gamma$–ray telescope sensitive to photon energy in the MeV-GeV regime
