Hi, Brian,

>>> Be careful:  if this is the source paper for the data you
mention, then the VRI results are already on the Cousins system!
The Moreno & Carrasco data were reduced directly against Graham
E-region standards, so there was no Johnson R,I anything involved.
The two-color plots shown in the paper do involve transforming
standard relations by Johnson to the Cousins system, but that was
necessary because their VRI data are Cousins colors.


Understood. Fortunately the conclussion is the same, the data are Rc and Ic.
Thanks for the clarification.

Cheers,
Sebastian
