Function Documentation

collect_hits()

void collect_hits	(	hitmap_t &	hits,
		const std::string	filename,
		int	channel,
		const std::string	calibfilename
	)

open input file and get tree

create hit and connect variables to branches

open calibration file and load calibration parameters

loop over tree entries

increment spill

reset start of spill

must be ALCOR hit

from the desired channel

calculate corrected time

define frame

push hit

close input file

signal_basic()

void signal_basic	(	const std::string	reference_filename,
		int	reference_channel,
		const std::string	reference_calibfilename,
		const std::string	target_filename,
		int	target_channel,
		const std::string	target_calibfilename,
		const std::string	outfilename
	)

collect hits from reference and target data

loop over reference frames

loop over reference hits in frame

loop over target hits in frame

normalise to number of triggers

apply geometrical acceptance function to obtain corrected distribution
