The offsets can be from hkl values in a range of hkl values or from peaks in the input PeaksWorkspace

This Algorithm creates a PeaksWorkspace with peaks occurring at specific fractional offsets from h,k,or l values.
There are options to create Peaks offset from peaks from the input PeaksWorkspace, or to create peaks offset from h,k, and l values in a range. Zero offsets are allowed if some or all integer h,k, or l values are desired. The order can be 1 for +/-1 or 2 for +/-1 and +/-2, etc.
The input PeaksWorkspace must contain an orientation matrix and have been INDEXED by THIS MATRIX when the new peaks are not created from a range of h ,k, and l values
Example:
peaks = LoadIsawPeaks("TOPAZ_3007.peaks")
LoadIsawUB(peaks,"TOPAZ_3007.mat")
IndexPeaks(peaks)
fractional_peaks = PredictSatellitePeaks(peaks, ModVector1=[-0.5,0,0.0], MaxOrder=1)
print("Number of fractional peaks: {}".format(fractional_peaks.getNumberPeaks()))
Number of fractional peaks: 122
