seeing by Fourier Transform
Posted: Sat Sep 01, 2018 10:20 am
It seems to me that a good measure of astronomical seeing is by using the Fourier Transform spectrum of the position of a random pixel as a function of time from in a movie - eg amplitude and frequency content - low amplitude good and low frquency good and so-on. I could do this if I could understand the format of an avi-file - ie extract the information and then FT it.
Surely a simple task to someone familiar with avi files ?
Any thoughts ?
