Sectors

Root

Txt

Using the line:

awk -F'|' 'BEGIN{print "count", "lineNum"}{print gsub(/4/,"") "\t" NR}' Molr.txt > temp.dat

Using the fact that the 472 line of the Molr.txt file corresponds to the sector number, we can find:

awk 'NR-1==472{print $1}' temp.dat

This gives us the number of times hit were detected in sector 4 as:

37

Similarly, for Sector number 1:

awk -F'|' 'BEGIN{print "count", "lineNum"}{print gsub(/1/,"") "\t" NR}' Molr.txt > temp.dat

Using the fact that the 472 line of the Molr.txt file corresponds to the sector number, we can find:

awk 'NR-1==4712print $1}' temp.dat

This gives us the number of times hit were detected in sector 1 as:

39

Accounting for the two occurances of "1" in the line header (1302,1) representing the bank and subbank, we find that there are

37

This gives the total number of hits as 74 as expected.

Superlayers

Root

Txt

awk -F'|' 'BEGIN{print "count", "lineNum"}{print gsub(/1/,"") "\t" NR}' Molr.txt > temp.dat

awk 'NR-1==473{print $1}' temp.dat

13

Accounting for the 1 within the header (1302,2), we find 12

Using similar expressions for the remaining superlayers, and accounting for numbers which appear in the header (1302,2):

Numbers of Superlayer Hits

Superlayer	Count	Adjusted Count
1	13	12
2	14	12
3	13	12
4	12	12
5	13	13
6	13	13

This verifies the Superlayer counts.

Layers

Root

Txt

Using the line:

awk -F'|' 'BEGIN{print "count", "lineNum"}{print gsub(/1/,"") "\t" NR}' Molr.txt > temp.dat

Using the fact that the 474 line of the Molr.txt file corresponds to the layer number, we can find:

awk 'NR-1==474{print $1}' temp.dat

This gives us the number of times hit were detected in layer 1 as:

14

Accounting for the header (1302,3), this count becomes

13

Similarly, for layers 2-6:

Numbers of Layer Hits

Layer	Count	Adjusted Count
1	14	13
2	14	13
3	14	12
4	12	12
5	12	12
6	12	12

This verifies the layer counts.

Wires

Root

Txt

Using the line:

awk -F'|' 'BEGIN{print "count", "lineNum"}{print gsub(/52/,"") "\t" NR}' Molr.txt > temp.dat

Using the fact that the 475 line of the Molr.txt file corresponds to the wire number, we can find:

awk 'NR-1==475{print $1}' temp.dat

This gives us the number of times hit were detected in wire 52 as:

5

Similarly, for wires 53-60:

Numbers of Wire Hits

Wire	Count	Adjusted Count
52	5	5
53	8	8
54	12	12
55	1	1
56	0	0
57	0	0
58	0	0
59	24	24
60	0	0
61	0	0
62	0	0
63	24	24

This verifies the wire counts.
