G. Pietrzyński led a 2013 measurement of the Euclidean distance to the Large Magellanic Cloud using eight late-type eclipsing binaries. The systems contained cool giant stars, whose physical and angular sizes could be compared to infer Euclidean distance.

The study reported approximately $2.2\%$ accuracy and kept statistical and systematic uncertainties separate. Choosing these systems addressed modeling difficulties associated with hotter binaries, while improving an anchor of the cosmic distance ladder and hence the calibration of the Hubble constant.^[ref]
