Please let me know if you know about any good de-trending IDL algoritms
for use with the IDL FFT algorithm.
The objects under study are a bit truncated by the finite size of the image
and these abrupt gradients tend to pollute the resulting DFT, obscuring the
detail of interest to me.
Any hints are welcome.
Sincerely,
Trond
