Scientific paper
The paper contains 4 catalogues that are archived electronically: The first and most important one is the catalogue of 70 high probability and 1422 candidate optically bright post-AGB stars in the LMC. For this, we performed a cross-correlation with three optical catalogues and data from 2MASS and SAGE. The estimated luminosity and some cross-correlation remarks with catalogues of other types of objects that have a chance of occuring in our catalogue are also listed. For the 70 objects for which we obtained a spectrum we also give the spectral type and some information on the variability of the source. This catalogue offers strong potential in the study of mass-dependant properties of post-AGB stars such as AGB nucleosynthetic yields via photospheric abundances studies, and mass-loss rates by the distribution of post-AGB stars in the HR diagram.
One additional catalogue lists objects for which a low-resolution optical spectrum was obtained, but that are no longer part of our final catalogue of post-AGB candidates. Part of this catalogue appears as an online table in the article, but some extra information is listed here.
The last two catalogues contain objects that were discarded based on their too high or too low luminosity but that may be of interest for people studying respectively supergiants or young stellar objects in the LMC as they show similar IR colours.
