4 The catalogue

The fourth catalogue of LMC ${\rm W}-{\rm R}$ stars is presented in Table 2 and contains 134 objects; each of them has been, at least once, assigned a ${\rm W}-{\rm R}$ type. The miscellaneous designations of the stars from discovery papers are given in Table 3. Finding charts for all the stars appearing in the catalogue are provided in Figs. 2-12.

Table 2: Format of stellar data

Column 1: Running catalogue number.

Column 2: The designation "Brey" refers to the third catalogue of LMC ${\rm W}-{\rm R}$ stars published by Breysacher (1981). The letters "a'', ``b'' and ``c'' denote the stars subsequently included in this catalogue.

Column 3: Equatorial coordinates for J2000.0. The accuracy is $\pm 0.045$ s in right ascension, and $\pm 0.20$ arcsec in declination.

Column 4: v magnitude in narrow-band photometry in Smith's (1968b) system. Boldfaced values correspond to the original measurements by Smith (1968b), the other values are Johnson V magnitudes corrected for emission line contamination using the correction factors determined by Breysacher (1986). When available, the synthetic v magnitude derived by Torres-Dodgen & Massey (1988) is given in parentheses. Sources for the V magnitudes are as follows:

a: Rousseau et al. (1978)
b: Azzopardi & Breysacher (1979, 1980, 1985)
c: Feitzinger & Isserstedt (1983)
d: Morgan & Good (1985, 1987, 1990)
e: Bohannan & Walborn (1989)
f: Lee (1990)
g: Schild & Testor (1992)
h: Parker (1993)
i: Testor et al. (1993)
j: Malumuth & Heap (1994)
k: Spoon et al. (1994)
l: Schertl et al. (1995)
m: Walborn & Blades (1997)
n: Morgan (1999)
o: present work.

Column 5: b-v colour in narrow-band photometry in Smith's (1968b) system. Boldfaced values correspond to the original measurements by Smith (1968b), the other values are the synthetic colours derived by Torres-Dodgen & Massey (1988).

Column 6: Spectral classification. The reference number given in parentheses refers to the source (cf. Col. 7).

Column 7: Bibliographical references for the spectral classification of the star. The sources, in chronological order, are codified as follows:

60: Feast et al. (1960)
68: Smith (1968b)
76: Fehrenbach et al. (1976)
77: Walborn (1977)
78: Melnick (1978)

89c: Moffat (1989)
90a: Moffat et al. (1990)
90b: Smith et al. (1990a)
90c: Morgan & Good (1990)
90d: Heydari-Malayeri et al. (1990)
90e: Testor & Schild (1990)
91a: Niemela (1991)
91b: Pakull (1991)
92a: Schild & Testor (1992)
92b: Heydari-Malayeri & Melnick (1992)
93a: Heydari-Malayeri et al. (1993)
93b: Testor et al. (1993)
94 : Heap et al. (1994)
95a: Bartzakos et al. (1995)

97b: Walborn & Blades (1997)
98a: Massey & Hunter (1998)
98b: Crowther et al. (1998)
98c: Crowther & Dessart (1998)
98d: Testor & Niemela (1998)
98e: Morgan (1999)
98f: Bartzakos (1998).

Column 8: Binarity of the star. SB1 and SB2 designate, as usual, the single-lined and double-lined spectroscopic binaries respectively. The number in parentheses refers to the source (cf. Col. 7). A question mark (?) indicates that binarity remains to be confirmed.

Column 9: OB association, as defined by Lucke & Hodge (1970), to which the ${\rm W}-{\rm R}$ star very likely belongs.

Column 10: Emission nebula where the ${\rm W}-{\rm R}$ star lies. Both the Henize (1956) number - when available - and the DEM (Davies et al. 1976) number are given.

Column 11: Notes on individual stars are indicated with an asterisk. The presence of two asterisks identifies the few objects for which the classification varies from ${\rm W}-{\rm R}$ to non ${\rm W}-{\rm R}$ in the literature, or is controversial.

Table 3: Format of designations

To comply with the IAU nomenclature recommendations, the first line in Table 3 refers to the designations adopted in the Dictionary of Nomenclature of Celestial Objects. Only the acronyms in Cols. 12, 16 and 20, proposed here for the first time, are not yet "official'', and therefore appear between parentheses. On the second line, when different, the more traditionally used acronyms are given for convenience. The designations, in chronological order from Col. 2, are listed in Table 1.
