Our trial
revision of the GCVS data for several southern constellations show that type changes are not needed for most
stars.
In the existing scheme, there can be combined types (like UV+BY), meaning the same star simultaneously having properties of two or more types.
We suggest to add one more symbol combining types, in the cases when two or more classification options remain for the same star, for example, EC|Ell, EC|RR (here EC means a contact eclipsing binary, this is one of our suggestions from next slides). This
symbol will permit us to have more
information in the main GCVS Table, people do not
read remarks very attentively. Moreover, it will simplify moving stars from the suspected-variable catalogue to the GCVS.
