... Previous: Predictive Mining of Time Series Data in Astronomy . ... This paper describes a method for determining the geometric distortion of the FUSE detectors using data from the in-orbit stimulation lamp exposures. A wavelet approach is used to smooth the image, while enhancing the shape of the shadows cast by the QE and plasma grids suspended above the detectors. ... Wavelets are functions that satisfy certain mathematical requirements and are used in representing data or other functions. ...
