We show results allowing a comparison of the EFM and FFM methods:
All observations for night 2456003 have been reduced to DS/(total flux) for both EFM and FFM method, and a direct albedo determination is also available from the FFM. The DS/total values are of course proprtional to terrestrial albedo and are plotted as crosses (FFM) and boxes (EFM) above. The line is the direct albedo estimate from the FFM method. Values have been normalized to a scale near 100.
The spread is near 5% but the standard deviation of the mean would be near 0.5-1%. If these numbers represented all data from one night we would be in line with BBSO claims, or slightly better.
Analysis of the BBSO method on these data awaits.
