\caption{\label{SPB-BULGE-param}Basic light curve and physical properties of Galactic Bulge stars classified as SPB with the GM method. The dominant frequency~$f_1$, the second frequency $f_2$ and the $V-I$ colour index are listed. Several of these stars might be evolved pulsators, termed PVSG here, rather than~SPB.}
