2006 IceCube-9 Flasher Runs

Elimination of IceCube flasher runs proved more challenging in 2006 due to the very large number of runs and incomplete logging. Flasher runs were compiled from a PSU C&V log and testdaq log files. The following is a table of run periods between Feb. 15 and Oct. 31 2006.

The flasher cuts are graphed below along with those used in the Zeuthen 2006 analysis and the difference between the two sets of cuts.

The sets of cuts are similar, but show minor differences. The periods cut by this analysis and not by Zeuthen are mostly non-flasher TestDAQ runs. It is clear from the above plot how often we took flasher data in 2006!

To evaluate the L3 sample for possible contamination with IC-9 flasher runs, the L3 event rate is plotted in 1000 second bins, which is similar to the length of a typical flasher run.



No unusual rate spikes are observed. Drops in rate are peroids where files have been rejected. The change in mean rate is due to seasonal atmospheric variations.

Comparison to 2005

Comparison plots include AMANDA string-trigger-only events, present in the L3 stream for 2005 and 2006.



Signal and atmospheric neutrino simulation is identical in structure to 2005, using 2006 detector parameters
