with model $phabs*zpowerlaw$ and the fluxes were calculated using [cflux]{}. The best-fit parameters given in Table 3 were derived for individual observation with a neutral hydrogen column density fixed to its Galactic value 1.99$\times10^{20}$ $cm^{-2}$ obtained from NASA/IPAC Extragalactic Database (NED)[^3]. The best fit average parameters were also derived using simultaneous fitting of the spectra of six observations.

The source 1ES 1218+304 was observed with *Swift*-UVOT using all filters (V, B, U, UVW1, UVM2, UVW2) in image mode over six days during $TACTIC$ observations. The image mode level II data of all the filters were used in the present analysis with latest calibration files of UVOT [@Breev11]. The data were processed with the standard procedure[^4] using [uvotmaghist]{} task of [heasoft]{} package. The UVOT source counts were extracted from a $5^{\prime\prime}$ sized circular region centered on the source position, while the background was extracted from a nearby larger, source free, circular region of $10^{\prime\prime}$ radius. The observed magnitudes were converted into fluxes using conversion factors given in [@Pool08]. The observed magnitudes obtained in six filters during the period from March 1, 2013 to April 15, 2013 are reported in Table 4.
