At present, WWLLN data are being combined with lightning data collected by Earth Networks, which greatly increases the overall lightning detection efficiency of the existing WWLLN. (eos.org)
CoRoT candidate abundances in the range of 0.1 - 0.4 % are significantly lower, probably due to an observed trend indicating fewer diluted binaries than predicted, where as for even lower amplitudes, low detection efficiencies begin to dominate. (aanda.org)
The total measured detection efficiency including the sky, telescope and fiber transmission losses, the instrument and iodine transmission losses and detector quantum efficiency is 3.4 % under 1.5 arcsec seeing conditions, which is comparable to all of the echelle spectrometers for planet detection.
