The light curve of the R Coronae Borealis star NSV 6708 (V854 Centauri) and the accuracy of visual estimates.

LAWSON W.A. and BATESON F.M.

Abstract (from CDS):

The R Coronae Borealis start NSV 6708 (V854 Centauri) has been monitored by visual observers for over four years and photoelectrically for two years. The comparison of the visual estimates and the photoelectric data offers some insight into the potential of accuracy of visual light curves. We also make some suggestions about the selection of comparison sequences and sources of error in visual estimates.
