Detailed Description

Calculates the signal-to-noise ratio using old default algorithm.

This default implementation of the Profile::snr method is taken from the old timer archive code. Using Profile::find_min_phase and Profile::find_peak_edges, this function finds the integrated power in the pulse profile and divides this by the noise in the baseline.
