Analytical and Numerical Flash-Algorithms for Track Fits
  Flash-algorithm track-reconstruction routines with speed factors 3000-4000 in excess those of traditional iterative routines are presented.   The methods were successfully tested in the alignment of the Test Beam setup for the ATLAS Pixel Detector   MCM-D modules yielding a   60 fold increase in alignment resolution over iterative routines, for the same amount of alocated CPU time.
