6 Other variables

In addition to the Cepheid variables reported in our field, 333 other variable stars are also found in the present study. Most of them appear to be irregular variables. Only 115 stars are found periodic for which we could determine approximate period and magnitude. In Table 5, available in the electronic form either from authors or at the CDS, we have given the identification number, celestial coordinates, mean magnitude in R and I filters, amplitude variation and nature of these 333 stars in R filter. Out of these 333 stars, 32 were already categorized (see Table 5). V176 and V284 are suspected as a binary and light curve for one of them is shown in Fig. 7a. We have given the light curve of a periodic star V154 with period $\sim$236 days in Fig. 7b while the light curve of an irregular variable V252 is shown in Fig. 7c.
