Daca se folosesc doar primele doua numere, atunci e formatul din Guide Star Catalog si se marcheaza cu "GSC".

TYC 4771-1196-1
GSC 04771-01196

The designation of an object in the Tycho Catalogue uses the Guide Star Catalog numbering system 'FFFF-NNNNN' (a region number (FFFF) and a number within the region (NNNNN)) followed by a Tycho specific component number (N).


Eu, la duble, prefer The Washington Double Star Catalog, numerele reprezinta coordonatele:

WDS J05387-0236AB

This is the WDS identifier constructed from the J2000 coordinates by the WDS creators at the USNO. Thus, a binary with a WDS identifier of '05387-0236' has (approximate) J2000 coordinates of RA = 05 hrs 38.7 mins, Declination = -02 deg 36 mins. 

Spor la dedublari !  :)
