fine_fill()

TH2 * fine_fill

(

std::vector< std::string >

filenames

)

histogram with fine distribution

loop over input file list

open file

retrieve tree and link it

loop over events in tree

only ALCOR hits

fine_histo()

TH1 * fine_histo	(	TH2 *	hFine_all,
		int	index
	)

get_index()

int get_index	(	int	fifo,
		int	pixel,
		int	column,
		int	tdc
	)

example of usage:

root [0] .L fine_analysis.C root [1] TH2 *hFine_all = fine_fill({"alcdaq.fifo_0.root", "alcdaq.fifo_1.root"}); — opening decoded file: alcdaq.fifo_0.root — found 2151601 entries in tree — opening decoded file: alcdaq.fifo_1.root — found 1875405 entries in tree root [2] hFine_all->Draw("colz"); root [3] TH1 *hFine_0 = fine_histo(hFine_all, 0); root [4] hFine_0->Draw();

4 TDCs for each pixel 4 pixel for each column 8 columns for each chip
