Please put the variable's designation into field in common style - for example: ZUMa, zuma, V477Cyg, v1182Cyg, NSV 255, nsv2544. Designation of bright variable stars like Beta Persei type in short style (three letters) - bet Per. The complete cross-identification among more then 30 catalogues will be done after submitting.
Spaces and cases are ingnored..
