Error-weighted mean percental and mean statistical deviation of the flux normalization parameter, f, without (red dot) and with (blue dot) LIDAR corrections for eight zenith and aerosol transmission T_{9 km} bin combinations. The error ellipses are given by the shaded area. Note that, by construction, the uncertainty ellipses may not pass through the coordinate system origin, reflecting reconstruction biases. The number of averaged nights, n, is provided in the top-right corner of each plot. In the low aerosol transmission and high zenith bin, sufficient data are not available.
