Datatype: MKK

The spectral classification is basically separated in two datatypes
The MKK classification
It refers to the usual MKK bidimensional classification. The datatype is named mkk
HD-like spectral types
The one-dimensional Harvard spectral type (in the HD form) are collected under the datatype spt
Selected MK types
When many classifications exist in a cluster, a selection on the authors has been performed to keep only one type per star. Therefore, a variant has been introduced and this datatype is named mks.
