Table A.1: Parameters of galactic B[e] supergiant candidates. For each object we provide the ranges in luminosity and temperature as found in the literature. We further indicate for each target whether CO band emission has been detected in their K band spectra. A question mark means that no CO band emission was detected for $R\sim 450$.
