• DATA
  • Table 1 - Fourier parameters for 1423 ASAS RRab stars. The columns contain the ASAS ID of a star, number of harmonics N (ranging from 6 to 10), and a series of Fourier parameters with their errors, from 0 to N: a0, a0_err, a1, a1_err, phi1, phi1_err, ..., aN, aN_err, phiN, phiN_err. The variable number of harmonics means that the file has a variable number of columns. For example, for a 6 harmonic lightcurve (N=6), the number of columns is 28 (4*(N+1)).
  • Table 2 - The file contains 15 colums: ASAS ID, RA [h], Dec [deg], l [deg], b [deg], P [days], HJD-2450000 [days], V_min [mag], V_max [mag], V_avg [mag], Amp_V [mag], I_min [mag], I_max [mag], I_avg [mag], Amp_I [mag]
  • Table 3 - Metallicity information on a sample of 1008 ASAS RRab variables. The file contains 7 columns: ASAS ID, [Fe/H] from the JK96 method and its error, [Fe/H] from the S04 method, [Fe/H] for the NSVS counterpart (calculated by Kinemuchi et al. 2006), and finally spectroscopic value of [Fe/H] from Layden (1994) and its error.
• Lightcurves
  • An up-to-date V-band lightcurve for an individual star can be found via the ACVS Catalogue search form.
  • A pack of all lightcurves used in this paper will be provided on request.
