Multi-channel  analysis

So  far  several  groups  in  LSC(including  KGWG)  have  made  their  efforts  on  a  post-processing  analysis  (mainly  Veto)  to  distinguish  whether  triggered  events  are  glitches  or  not.

Our  project  focuses  on    a  tool  useful  for  commissioning.

9

Goal:  Development  of  a  method  for  localizing  noise  sources  using  auxiliary  channels  and  PEMs.Support  to  kill  noise  sources  

We  discussed  with  K-detchar  on  our  collab.  projects  and  set  our  goal  in  last  Dec.  and  this  Feb.

Multi-channel  analysis

Event  detection  pipelines  (K)

Future  selection  statistics  (t-  or  z-  statistics)  (K)

To  measure  channelsʼ’  responsibility  for  noise  events(J)

Classification  of  noise  events  (J)

Integrating  these  information,  localize  the  noise  sources.

10

Develop  the  pipeline  using  CLIO  data,  and  LIGO,  Virgo  data.

o  First  exam  is  to  localize  hardware  injection  we  generated  during  last  CLIO  operation.

o  Other  exams  are  to  do  same  for  noise  identified  already  in  LSC

Others

There  are  several  discussionsThe  Shadow  monitor  to  reduces  effects  of  violin  modes.→Particularly,  burst  searches  should  be  improved.Evaluate  what  impact  the  monitor  gives  on  data  analysis?Correlated  environmental  noise  in  global  detector  network.→Stochastic  GWB  search  should  be  affected.Calibration  accuracy
