fluctuation analysis

1. Average profile zoom works:

we use Matplotlib window (ginput) to read click location.
two clicks are used to mark pulse window.

fluctuation spectrum analysis

I am writing Python code to analyse single-pulse data from radio pulsars. The idea is to make polar maps from fluctuation analysis.

1. I can read data from Arecibo
2. display average profile, and
3. plot single-pulse sequences from the file.
