Function Documentation

collect_hits()

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

open input file and get tree

create hit and connect variables to branches

open calibration file and load calibration parameters

temporary hit vector

loop over tree entries

end of spill

sort hits in increasing time order

push hits to the output hit map

reset start of spill

must be ALCOR hit

from the desired channel

calculate corrected time

define frame

push hit

close input file

signal_aps()

void signal_aps	(	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
