TS_HANTS function question [message #93655]

Hello,
I am in the process of using the new TS_HANTS function and would like to verify that my understanding of its use is accurate.

Does the TS_HANTS function fit a harmonic (order determined by the NUM_FREQUENCIES keyword) to a specified time series? For example, I have a 365 day annual rainfall climatology at a specific location and would like to calculate and plot the 3rd harmonic of the time series. I have used the following for calculation:

harmonic3 = TS_HANTS(rainfall,NUM_FREQUENCIES=4)

I gather that NUM_FREQUENCIES = 1 is simply a horizontal line and 2 is the actual first harmonic. Are my assumptions above correct? If so, this new function is a miracle to use!

Thank you for your help. Much appreciated.
