Overview

The MESE Filter has a rate of 2.3 Hz.

Technical Documentation

• Inputs

  • This filter will run on InIceSplit subevent streams.

  • The SplitInIcePulses pulse series, which is a split, but uncleaned, pulse series.

  • This filter will run on events with these tags in the OnlineFiltermask:

    • OnlineL2Filter_23

    • SoftwareSMT12Filt_23

• Outputs

  • The boolean MESEFilter_24 (if the filter has passed) is saved in OfflineFilterMask

  • OfflineMESEFilter_HESE_abvL5, an I3Bool signifying if the pulse series in that frame had >6000 PE of charge and a layer veto charge < 3. This is a boolean value needed in L5 of the MESE event selection.

• Important Modules:

  • Homogenized QTot

  • I3 Topological Splitter

  • VHE Self Veto

  • MESE specific: outer layer veto

An overview of the steps in the MESE Filter. Each step cuts on specific criteria.

Physics Documentation

• Hosted by the Diffuse Working Group

• Mese event selection depends on mesefilter_15 -> MeseFilter_24

• Publication of results in progress Wiki: SpectralBreak_PaperOutline

• Extending the MESE event selection to more years would be interesting

  • Event selection which combines tracks and cascades

  • Could be added to the combined fit effort
