Shower Filter Code - Oct. 30

I updated the CheckHealth function to include an option to not write health files.

The entire Chiquita array was operational during the period between August 2003 and May 2004.

Good showers, Aug 2003 - May 2004
Unfiltered text file of good showers
Filtered text file of good showers

Code used for getting a text file of "good" showers from the the complete list of shower data:

• uptime.cc - Finds time periods when all CIT sites were healthy. Output:
  • uptime_08012003_08312003.txt
  • uptime_08012003_08312003.root
  • uptime_09012003_09302003.txt
  • uptime_09012003_09302003.root
  • uptime_10012003_10312003.txt
  • uptime_10012003_10312003.root
  • uptime_11012003_11302003.txt
  • uptime_11012003_11302003.root
  • uptime_12012003_12312003.txt
  • uptime_12012003_12312003.root
  • uptime_01012004_01312004.txt
  • uptime_01012004_01312004.root
  • uptime_02012004_02292004.txt
  • uptime_02012004_02292004.root
  • uptime_03012004_03312004.txt
  • uptime_03012004_03312004.root
  • uptime_04012004_04302004.txt
  • uptime_04012004_04302004.root
  • uptime_05012004_05312004.txt
  • uptime_05012004_05312004.root
• totaluptime.pl - Finds the total time during the selected period that all CIT sites were healthy. (Prints to screen.)
• getshowers.pl - Gets list of showers from web page and makes a text file of times. Output:
  • August 2003 shower times
  • September 2003 shower times
  • October 2003 shower times
  • November 2003 shower times
  • December 2003 shower times
  • January 2004 shower times
  • February 2004 shower times
  • March 2004 shower times
  • April 2004 shower times
  • May 2004 shower times
• goodshowers.pl - Compares the output of getshowers.pl to the output of uptime.cc to make a list of showers that happened when all sites were online. Output:
  • aug03goodshowers.txt.
  • sept03goodshowers.txt.
  • oct03goodshowers.txt.
  • nov03goodshowers.txt.
  • dec03goodshowers.txt.
  • jan04goodshowers.txt.
  • feb04goodshowers.txt.
  • mar04goodshowers.txt.
  • apr04goodshowers.txt.
  • may04goodshowers.txt.
  These are concatenated into allgoodshowers.txt.
• makelinks.pl - Takes the output of goodshowers.pl and makes an html file of links to the good showers as well as a text file to feed to the following shell script. Output:
  • allgoodshowers.html (18388 showers).
  • links.txt
• doit.sh - Runs get.sh on all the search URLs in links.txt. (Call with "bash doit.sh links.txt".)
• get.sh - Runs wget on a search URL and passes the output to strip.pl and then to output.txt
• strip.pl - Strips html formatting from the page returned by the search URL
• filtershowers.pl - Takes a text file of shower data (output.txt) and removes accidentals (defined to be non-chiquita sites, sites hit more than 10 microseconds away from the trigger, and afterpulses arriving more than 1 microsecond after the first hit at a site). Output: filtered.txt. (Had to fix a bug in makelinks3.pl, which was skipping showers due to problems with daylight savings time.)

Of 18388 showers, 16075 are still showers after having all non-chiquita sites and accidentals removed. Of those, 14576 pass a cut on theta <= 45 degrees.
