=Verify with txt output=

==Sectors==

===Root===

<center>[[File:DC_SECTORS_ROOT.png]]</center>

===Txt===
Using the line:
<pre>
awk -F'|' 'BEGIN{print "count", "lineNum"}{print gsub(/4/,"") "\t" NR}' Molr.txt > temp.dat
</pre>

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

<pre>
awk 'NR-1==472{print $1}' temp.dat
</pre>

This gives us the number of times hit were detected in sector 4 as:
<pre>
37
</pre>


Similarly, for Sector number 1:
<pre>
awk -F'|' 'BEGIN{print "count", "lineNum"}{print gsub(/1/,"") "\t" NR}' Molr.txt > temp.dat
</pre>

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

<pre>
awk 'NR-1==4712print $1}' temp.dat
</pre>

This gives us the number of times hit were detected in sector 1 as:
<pre>
39
</pre>
Accounting for the two occurances of "1" in the line header (1302,1) representing the bank and subbank, we find that there are 
<pre>
37
</pre>

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

==Superlayers==
===Root===
<center>[[File:DC_SUPERLAYERS_ROOT.png]]</center>

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

<pre>
awk 'NR-1==473{print $1}' temp.dat
</pre>

<pre>
13
</pre>
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):


<center>
{| border=1 | center
  |+ 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
|}
</center>
This verifies the Superlayer counts.

==Layers==
===Root===
<center>[[File:DC_LAYERS_ROOT.png]]</center>

===Txt===
Using the line:
<pre>
awk -F'|' 'BEGIN{print "count", "lineNum"}{print gsub(/1/,"") "\t" NR}' Molr.txt > temp.dat
</pre>

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

<pre>
awk 'NR-1==474{print $1}' temp.dat
</pre>

This gives us the number of times hit were detected in layer 1 as:
<pre>
14
</pre>
Accounting for the header (1302,3), this count becomes

<pre>
13
</pre>

Similarly, for layers 2-6:
<center>
{| border=1 | center
  |+ 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
|}
</center>
This verifies the layer counts.

==Wires==
===Root===
<center>[[File:DC_WIRE_ROOT.png]]</center>

===Txt===
Using the line:
<pre>
awk -F'|' 'BEGIN{print "count", "lineNum"}{print gsub(/52/,"") "\t" NR}' Molr.txt > temp.dat
</pre>

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

<pre>
awk 'NR-1==475{print $1}' temp.dat
</pre>

This gives us the number of times hit were detected in wire 52 as:
<pre>
5
</pre>


Similarly, for wires 53-60:
<center>
{| border=1 | center
  |+ Numbers of Wire Hits
|-
  ! Wire
  ! Count
  ! Adjusted Count
|-
  | 52
  | 5
  | 5
|-
  | 53
  | 8
  | 8
|-
  | 54
  | 12

|-
  | 62

|-
  | 63

  | 24
|}
</center>
This verifies the wire counts.
