Screen shot of TADPOLE functionality.

The user selects the input TADPOLE data file, as well as the file containing the reference pulse. This can be an electric field in a disk file, or a field just recovered from a FROG trace. When the user clicks on the "FFT Data" screen, the vertical line, which signals the cutoff point for the data, moves to the new location. The TADPOLE algorithm then computes the new pulse, and displays it on the lower two screens, as well as its relevant widths on the top right screen.
