All Tables

• Table 1: The range of estimated apparent visual distance modulus (), obtained with different methods, and the reddening values, E(B-V), provided in the recent literature for M3. The [Fe/H] values given by Zinn & West (1984: ZW), Harris (2003: H) and Carretta & Gratton (1997: CG) are also reported.
• Table 2: Observed characteristics of the selected sample of variables. From left to right one finds the star identification, the period in days, the intensity averaged V magnitude, the intensity averaged B-V color and the RR type.
• Table 3: Accepted ranges of the physical parameters (mass, luminosity and effective temperature) for variables V128, V126, V72 and V152, together with the corresponding range of apparent visual distance modulus and intensity weighted (B-V) color. For the V152 variable the range in temperature (color) has not been calculated (see text).
• Table 4: Evolutionary masses and luminosities predicted by different sets of ZAHB models for a mean effective temperature of 7000 K, obtained from our best fit pulsational models (see text). The selected evolutionary papers are: V00, VandenBerg et al. (2000); DC02/C05, D'Antona et al. (2002) and V. Caloi (2005, private communication quoted in MC05); P04, Pietrinferni et al. (2004); CDC04, Cariulo et al. (2004).
• Table 5: Physical parameters of V128, V126 and V72 variables as derived by Cacciari et al. (2005) from color-temperature calibration.
