/* The following function finds the optimal shift for the FF 
   in order to use them as a physical model for the perpendicular
   shape of the PSF on the CCD by calculating the correlation 
   between Science Frame and FF. The correlation takes place between 
   a synthetic frame with gaussian-shaped fibres centered on 
   shifted fibre positions and the actual, real frame on which the shift is
   to be found. In this version, the shift is searched separately for
   the fibres present in each of the frames composing the SingleFF structure, 
   with respect to what is supposed to be an all fibres flat field frame.
   The y shifts are returned in the ydelta vector, and the deltamask vector
   is set to TRUE for the frames for which a well defined shift was found, 
   FALSE for the frames for which no correlation maximum could be found 
   for whatever reason.
