  High-resolution spectroscopic searches for the starlight reflected from
close-in extra-solar giant planets have the capability of determining the
optical albedo spectra and scattering properties of these objects. When
combined with radial velocity measurements they also yield the true mass of the
planet. To date, only two such planets have been targeted for reflected-light
signals, yielding upper limits on the planets' optical albedos. Here we examine
the prospects for future searches of this kind. We present Monte Carlo
estimates of prior probability distributions for the orbital velocity
amplitudes and planet/star flux ratios of 6 bright stars known to harbour giant
planets in orbits with periods of less than 5 days. Using these estimates, we
assess the viability of these targets for future reflected-light searches using
4m and 8m-class telescopes.
