... accuracy

The numerical values used in these formulæ and in orbital solutions derived by FOTEL are based on the solar bolometric magnitude of +4 $^{\hbox{$.\!\!^{\rm m}$ }}$75, accurate value of solar mass of ( $1.988435\pm0.000027)\times 10^{30}$ kg and the gravitational constant $G=(6.674215\pm0.000092)\times 10^{-11}$ m³ kg^-1s^-2 derived by Gundlach & Merkowitz (2000) and on the solar radius of $6.95835\times 10^8$ m derived by Harmanec from a fit of numerous measurements of the solar angular radius available in the astronomical literature (to be published).

... amplitude

Note that line intensity variation from KOREL can reflect continuum variations but cannot be directly considered to be identical to a standard light curve - see Hadrava (1997) for details.
