TACTIC Data Analysis
--------------------

Apart from excluding the observations during bad atmospheric conditions, several standard data quality tests have been applied to the raw data for selecting clean data for further analysis. The data quality checks include the following: compatibility of the prompt coincidence rates with the expected zenith angle behavior, Poission distribution for arrival times of prompt events and steady behavior of chance coincidence rates with time. After applying the above data quality checks the final data sample reduces to $\sim$ 39.62 h. For gamma/hadron separation we have followed the standard Hillas parameter analysis [@Hill85] where each Cherenkov image is characterized by its moments. In this procedure each Cherenkov image is characterized by various image parameters like *length* (L), *width* (W), *distance* (D), *alpha* ($\alpha$), *size* (S), *frac2* (F2) and *asymmetry* (ASYM). This technique was later refined to Dynamic Supercuts procedure where $S$ dependent shape parameters of the image as well as its orientation were used for segregating the $\gamma$–rays from the background cosmic–rays [@Hill98; @Moh98]. The $\gamma$–ray selection criteria used in the present work are given in Table 2. These cuts
