3147 III/147 Studies of LMC stellar content J M Rousseau N Martin L Prevot E Rebeirot A Robin J P Brunet Astron. Astrophys. Suppl. Ser. 31 243 1978 1978A&AS...31..243R Magellanic Clouds This is an updated version of the original catalogue. New UBV photoelectric measurements were added from Isserstedt (1979, 1982), and Feitzinger and Isserstedt (1983). The remarks and origins of photoelectric photoelectric magnitudes are not included in this electronic version. Photoelectric data are obtained by averaging observational values made at 100 and more cm instruments (with weight=2) with ones made at 60 and less cm instruments (with weight=1). A spectral survey has been made during the period 1971 to 1975 with the ESO 40cm astrograph at La Silla, equipped with its normal prism, giving an intermediate dispersion of 95Angstroem/mm at 4026Angstroem. Long exposure plates taken directly or with an interference filter enabled us to obtain spectral types for nearly 1600 stars. In parallel, a V photographic survey has been carried out during the same period with the same astrograph and has led to the determination of V magnitudes for more that 700 stars having no previous photometric data. New spectroscopic and photometric results as well as previous photoelectric UBV values are given in the catalogue together with additional remarks concerning peculiarities of spectra, V magnitudes, and details on double and multiple systems.
