2 Otero, Sebastian Alberto 2007-09-01 07:14 UTC The original GCVS reference already states the R nature of the variable and the lack of photometric confirmation of the BCEP variability.
Schrijvers and Telting (2002) confirm that the variability is only spectroscopic. The light variation is just reflection at the orbital period.
Hipparcos lightcurve, position, range and epoch added.
