Cat. J/A+A/312/111) and Kovacs & Kanbur (1998MNRAS.295..834K 1998MNRAS.295..834K) as the
maximum value among several combinations of coefficients; it represents
a quality test on the regularity of the shape of the light curve.

Global Notes:
Note (G1): Cl* NGC 5272 Saw VNNN in Simbad.
In original table, Cl* NGC 5272 Saw V258 was identified by KG14.
Note (G2): The mean magnitude is derived by integrating the light curves
in intensity and converting the result of this integration to magnitudes.
Note (G3): The rise time value is defined as the phase intervals between
the minimum and maximum light.
Note (G4): Each star is listed at least twice: the first line refers to the
Corwin & Carney (2001AJ....122.3183C 2001AJ....122.3183C) 1992 data, the second line to
the 1993 data. When available, also the data from Kaluzny et al.
(1998MNRAS.296..347K 1998MNRAS.296..347K) and Carretta et al. (1998MNRAS.298.1005C 1998MNRAS.298.1005C) are
listed, as indicated in n_Saw.
Note (G5): The mass-luminosity parameter is:
A = 0.81log(M)-log(L)=13.353-1.19log(P0)-4.058log(T).
