All Tables

Table 1: Fundamental properties of NGC 6791: right ascension, declination, age, distance modulus, metallicity, and reddening. The values are taken from Chaboyer et al. (1999) except the metallicity which is from Taylor (2001). Note that the quoted errors are probably too optimistic and do not include systematic errors (except the error on the metallicity).
Table 2: Log of observations of NGC 6791 from three campaigns. The columns contain the adopted abbreviation of the campaign, the name of the telescope, the duration of the campaign, the number of useful nights (n), the median seeing in the V filter, and the number of images obtained in each of the BVRI filters. The last column gives information on which reduction technique we have used. Note that we have not reduced the MOCH01 data set, but we have obtained the light curves of the variable stars published by Mochejska et al. (2002).
Table 3: We give the name, ID number, $\alpha$ , $\delta$ , V, V-I, and B-I for the stars with transit-like light curves. All information except the adapted name in the first column is from Stetson et al. (2003). The positions of the stars in the CMD is shown in Fig. 3 and the light curves can be seen in Fig. 4. As discussed in the text, the transits seen for T1-4, T6, and T9 are not likely to be due to transiting giant planets (they are marked by a * symbol).
Table 4: The variables in the NOT01 field. The first column contains the variable name, where the new variables are printed with italics ( V79-V100). Columns 2-4 contain ID, right ascension, and declination from Stetson et al. (2003). Columns 5 and 6 are the periods and amplitudes (in the V filter) we have determined. The last column gives the variable star type. The positions of the variables in the colour-magnitude diagram are given in Figs. 3 and 5 while the phased light curves of some of the stars are shown in Figs. 6, 7, and 8.
Table 5: The derived parameters for the two components of the binary star V20. We found the colours from Fig. 10, and in the text we explain how $T_{\rm eff}$ was determined. The estimated errors are given in parenthesis.
