Thank you Dennis,
                        But the link of archives did not work for me,
I did an fft of the original data and the one after removing the daily
mean annual cycle but I observe that both annual and semi annual
cycles are getting removed? I expected only annual cycle to be removed
am I correct in my assumption?
with best regards
Sudheer
