RATIO
Finds the ratio of two bands on any axis of an arbitrarily
dimensioned array. This could be used in the following ways:-
- 1D array, ratioed on ENERGY gives a hardness index for a
spectrum.
- 2D array, say TIME vs ENERGY. Ratio along TIME to give
relative intensity or along ENERGY to give a time series
of hardness values.
- 3D array, say TIME vs X,Y. Ratio on TIME to give
relative intensity of two images.
- 3D array, say ENERGY vs X,Y. Ratio on ENERGY to get
hardness map.
- 4D array, ENERGY vs TIME vs X,Y. Could get time sequence
of hardness maps ; a relative intensity of two spectral
image ranges and so on.
