We reanalyse the UV/optical spectrum and optical broad-band data of theeclipsing binary HV 2274 in the LMC, and derive its distance following themethod given by Guinan et al. (1998a,b) of fitting theoretical spectra to thestars' UV/optical spectrum plus optical photometry. We describe the method indetail, pointing out the various assumptions that have to be made; moreover, wediscuss the systematic effects of using different sets of model atmospheres anddifferent sets of optical photometric data. It turns out that differentselections of the photometric data, the set of model atmospheres and theconstraints on the value of the ratio of selective to total extinction in the$V$-band, result in a 25% range in distances (although some of these modelshave a large ${\chi}^2$). For our best choice of these quantities the derivedvalue for the reddening to HV 2274 is E(B-V) = 0.103 $\pm$ 0.007, and thede-reddened distance modulus is DM = 18.46 $\pm$ 0.06; the DM to the center ofthe LMC is found to be 18.42 $\pm$ 0.07. This is significantly larger than theDM of 18.30 $\pm$ 0.07 derived by Guinan et al. (1998a).Comment: Accepted by: Astronomy and Astrophysic
