Pattern Unit Statistics

The bit and pattern statistics for the pattern unit were determined for each run, spewcifically

how often each pattern bit fired
how often each bit combination was seen

The number of events with a given patten bit set as well as the count of any pattern bit combination has been determined for each run.

The data is available in the form of one file per run. It has a self-explanatory form like

########## URN 5010 ##########

---- Pattern Statistics ----
  pattern bit  0 0000000000000001 :  1306939
  pattern bit  1 0000000000000010 :  1306939
  pattern bit  2 0000000000000100 :   435914
  pattern bit  3 0000000000001000 :       20
  pattern bit  4 0000000000010000 :     3455
  pattern bit  5 0000000000100000 :       71
  pattern bit  6 0000000001000000 :        7
  pattern bit  8 0000000100000000 :  1306939

  pattern 0x0000 0000000000000000 :       15
  pattern 0x0103 0000000100000011 :   867563
  pattern 0x0107 0000000100000111 :   435894
  pattern 0x010f 0000000100001111 :       20
  pattern 0x0113 0000000100010011 :     3384
  pattern 0x0133 0000000100110011 :       71
  pattern 0x0143 0000000101000011 :        7

---- Statistics ----
  ORN:           5010
  HeadTime:      "11-FEB-99 15:15:48"
  NBuffer:          17548
  NEvent:         1306954
  NParam:        64117132
  NJbusBuffer:        282
  NScalerBuffer:        9
  NErrLabelRange:       0
  NErrLabelDupl:        0

From this example one sees immediately that in this run

were 1306954 events (NEvent line after "Statistics").
that bit 0, 1 and 8 fired for all but 15 events
that bit 2, 3, 4, 5, and 6 fired for some events
that for 15 events no bit was set
that e.g. 3384 events had bit 0, 1, 4 and 8 set.
