The standard grid for mass and radius determination through a maximum likelihood technique. The grid is computed assuming the solar scaled mixing-length value.

A data frames containing 9 variables:
The effective temperature of the star (in K).
The logarithm of the surface gravity of the star (in cm s^-2).
The metallicity [Fe/H] of the star.
The large frequency separation for the star (in unit of solar large frequency separation).
The frequency of maximum oscillation power for the star (in unit of solar frequency of maximum oscillation power).
The mass of the star (in unit of solar mass).
The radius of the star (in unit of solar radius)
The logarithm of the age of the star (in yr).
The ratio between the age of the star and the time needed for central hydrogen depletion for that star.
