.. py:function:: calculate_flux_error(datfile, stdev=4, size=1000, loc=75, scale=50)

   Estimate Error of spectrum based on Savitzky-Golay filtering over large area and subtracting form original data

   Parameters
   ----------
   datfile : str
       Path to spectral file of which to calculate flux error
   stdev : int
       Bins over which spectrum is smoothed. Standarddeviation in Gaussian kernel. Default: 4
   size : int
       Number of windowlengths to be drawn randomly. Default: 1000
   loc : int or float
       Mean of Gaussian distribution from which windowlengths are drawn. Default: 75
   scale : int or float
       Stdev of Gaussian distribution from which windowlengths are drawn. Default: 50

   Returns
   -------
   data_err : np.ndarray
   unnormalized error
