  Lutz-Kelker bias corrected absolute magnitude calibrations for the detached
binary systems with main-sequence components are presented. The absolute
magnitudes of the calibrator stars were derived at intrinsic colours of
Johnson-Cousins and 2MASS (Two Micron All Sky Survey) photometric systems. As
for the calibrator stars, 44 detached binaries were selected from the Hipparcos
catalogue, which have relative observed parallax errors smaller than 15%
($\sigma_{\pi}/\pi\leq0.15$). The calibration equations which provide the
corrected absolute magnitude for optical and near-infrared pass bands are valid
for wide ranges of colours and absolute magnitudes: $-0.18<(B-V)_{0}<0.91$,
$-1.6<M_{V}<5.5$ and $-0.15<(J-H)_{0}<0.50$, $-0.02<(H-K_{s})_{0}<0.13$,
$0<M_{J}<4$, respectively. The distances computed using the luminosity-colours
(LCs) relation with optical (BV) and near-infrared ($JHK_{s}$) observations
were compared to the distances found from various other methods. The results
show that new absolute magnitude calibrations of this study can be used as a
convenient statistical tool to estimate the true distances of detached binaries
out of Hipparcos' distance limit.
