Dear Sameer, the detail image in simple error map module should be typically one "hole" in the grating. In fact it only does correlation search, then finds local maxima in correlation and tries to fit them on ideal positions of holes. In principle this could be used for drift correction as well, but some questions would remain, e.g. how to extrapolate the values of correction coefficients if you want use it for the same datafield.
