Abstract
Lunar occultations provide measurements of stellar angular diameters, leading thus to a determination of their effective temperatures. Basically, the data reduction process relies on two methods: model fitting and deconvolution. “Integrated deconvolution”, presented here, is a derived method of deconvolution and its results can compare with the two methods. The purpose is to determine the variation of the uncovered surface of the source throughout the occultation instead of extracting the brightness profile of the source. The main advantage provided is that computing the signal derivative is no longer necessary. In addition to saving a lot of computing time, the method affords a good estimate of the apparent speed, precise dating, and the angular separation of double stars down to 0.002 arcsec. After being tested against the usual methods, “integrated deconvolution” is now currently used. Some results are presented here.
