Notes

^ This star is Gould's 25th of Crux in his Uranometria Argentina. (Gould, B. A., (2009) Uranometria Argentina, (Reprinted and updated by Pilcher, F.)[1]) Kostjuk (see below) erroneously lists it as "256 Cru". Confusingly it with "25G. Cru"?
^ This star is Gould's 39th of Crux in his Uranometria Argentina. (op. cit.) Kostjuk erroneously lists it as simply "39 Cru". SIMBAD follows this error in its object query result as " * 39 Cru -- Be Star".
^ This star is Gould's 35th of Crux in his Uranometria Argentina. (op. cit.) Kostjuk erroneously lists it as simply "35 Cru". SIMBAD follows this error in its object query result " V* BG Cru -- Classical Cepheid (delta Cep type)".
