Detailed Description

Class containing legacy functions to be removed in the future. Let me know if they are still in use.

Constructor & Destructor Documentation

Legacy_functions()

Legacy_functions::Legacy_functions ( int  no_of_bin_files_to_read )

inline

Initializer will call initializer of ReadRun class.

Parameters

no_of_bin_files_to_read

Parameter not yet implemented

Definition at line 11 of file Legacy_functions.h.

Member Function Documentation

FractionEventsAboveThreshold()

void Legacy_functions::FractionEventsAboveThreshold	(	float	threshold = 4,
		bool	max = true,
		bool	greater = true,
		double	from = 0.,
		double	to = 0.,
		bool	verbose = false
	)

Find events with max/min above/below a certain threshold.

Needs to be called before the charge spectrum etc functions.
Baseline correction should be called before this function. Sequential Clone() loop makes this inefficient. Please let me know if the function is still in use and should be updated.

Parameters

threshold	Threshold in mV.
max	If true uses max, else uses min.
greater	If true looks for events with max/min>threshold, else looks for events with max/min<threshold.
from	Start search at "from" in ns.
to	End search at "to" in ns.
verbose	Set true for extra verbosity.
