PyDDM.ddm_calc.get_FF_DDM_matrix

get_FF_DDM_matrix(imageFile, dts, submean=True, useBH_windowing=False)

This code calculates the far-field DDM matrix for the series of images in imageFile at the lag times specified in dts.

Parameters
  • imageFile – Either a string specifying the location of the data or the data itself as a numpy array

  • dts – 1D array of delay times

  • limitImsTo – defaults to None

  • every – defaults to None

  • shiftAtEnd – defaults to False

  • noshift – defaults to False

  • submean – defaults to true

Returns

two numpy arrays: the fft’d data and the list of times
