Global coincidences

From MariachiWiki

This is a table showing coincidences between schools based on data collected from the beginning of data taking (fall 2007) to Jun 12, 2008. A procedure selected all the timestamps closer than 100us. Two SB arrays (Physics building and NSL) are excluded from the consideration here because we have coincidences between them routinely, few times a day. No coincidences between one of them and any school were found. Other notes:

  • timestamps come in pairs. Additional information is attached to the first line of the pair, the second is filled with a placeholder -1 which means nothing.
  • "time.diff" is the time difference between timestamps (which is not seen in "date" column), in μs (microseconds)
  • "time.max" is the time calculated as distance_between_schools/c/sqrt(2) (c is the speed of light), in us. The distance in km is also shown in the last column ("km")
  • coincidences with time.diff > time.max is flaged by "*" ("fl" column)
