We fit the data for the binary-lens microlensing event MACHO 98-SMC-1 from 5different microlensing collaborations and find two distinct solutionscharacterized by binary separation d and mass ratio q: (d,q)=(0.54,0.50) and(d,q)=(3.65,0.36), where d is in units of the Einstein radius. However, therelative proper motion of the lens is very similar in the two solutions, 1.30km/s/kpc and 1.48 km/s/kpc, thus confirming that the lens is in the SmallMagellanic Cloud. The close binary can be either rotating or approximatelystatic but the wide binary must be rotating at close its maximum allowed rateto be consistent with all the data. We measure limb-darkening coefficients forfive bands ranging from I to V. As expected, these progressively decrease withrising wavelength. This is the first measurement of limb darkening for ametal-poor A star.Comment: 29 pages + 9 figures + 2 tables, submitted to Ap
