Datatype: VRIkpg
For historical reasons, the VRI photometry has produced several systems
which have quite similar, but the V-R and R-I indices are not exactly
in the same standard system. Therefore a datatype has been attributed to
each realisation of the VRI filter combination.
The datatype vrikpg refers to the VRI photographic photometry in the
system of Kron.
