  3. 1. Status of dataset delivery a. STAFF-SA On time… 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  4. On time… PPP waiting aux data 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  5. b. STAFF-SC, NBR and HBR mode DWF: OK CWF: still an effort… CCS: priority after CWF validation 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  6. 2. Delivery plan 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  7. 3. Status of software development • SA: • Data pipelines are operational. • An updated pipeline with new format + add of new calibration tables will be developed soon. • Warning: - PSD and SM data were formerly described to be in the ISR2 reference frame. Indeed it’s in SR2. - SM BB units are mV².m-².Hz-1 rather than nT² Hz-1. - SM BE units are mV².m-².Hz-1 rather than nT.mV.m-1.Hz-1. (conversion factor to SI units given in UG) 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  8. SC: • CWF pipeline was updated to fulfil CAA recommendations. HBR and NBR mode are now merged and some timing issues were corrected. The production pipeline was also optimized in order to be as fast as possible: Ex: one year (2002), NBR + HBR + merge + CEFpass = 7 days, with 10 CPU. ≃ 0.6h / GB. • CCS pipeline is under development, with a new data gaps management and will provide data both in GSE system (0.6 – 12.5 or 225 Hz) and in ISR2 system (0.1 – 12.5 or 225 Hz). 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  9. 4. Cross Calibration / new results 4.a : Raw transfer function for HBR mode • Experimental transfer function show problems near 50Hz and 100Hz • Ex: C3 – HBR • x component Hz 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  10. 4.b : Smoothed transfer function • Smoothedtransferfunction • Ex: C3 – HBR • x component Hz 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  11. 4.c : STAFF CWF NBR - FGM one event comparison SR2 • STAFF (25 Hz) • FGM (~23 Hz) Both in SR2 system FGM: CAA FULL STAFF: CWF <∆B/B>≃1% σ∆B/B ≃ 1% 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  12. 4.d : STAFF CWF NBR -FGM ten years comparison study (SR2 system) C1 (average cal) C2 C3 C4 Uncredible stability of the instruments over 10 years… FGM: CAA FULL (~23 Hz) STAFF: CWF (25 Hz) <∆B/B>≃1% σ∆B/B ≃ 5% ≃ Or ~ a few nT for low fields 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  13. Scale: ~1 hour 4.e : STAFF HBR-FGM burst mode 5 mn C1 – SR2 • STAFF (450 Hz) • FGM (~66 Hz) Both in SR2 system FGM: CAA FULL Burst mode STAFF: CWF HBR mode <∆B/B>≃1% σ∆B/B ≃ 6% STAFF Bz does not see DC field but agreement on fluctuations GOOD !! 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  14. 4.e : STAFF HBR-FGM burst mode - Scale: ~ 5 mn 30s C1 – SR2 • STAFF (450 Hz) • FGM (~66 Hz) FGM: CAA FULL Burst mode STAFF: CWF HBR mode <∆B/B>≃1% σ∆B/B ≃ 6% Still good agreement on fluctuations 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  15. 4.e : STAFF HBR-FGM burst mode Scale: ~ 30s 2s C1 – SR2 Low frequency agreement in spin plane depend on B polarisation 10 s  0.1 Hz (Will bedetailled in next version of CR and paper) <∆B/B>≃3% σB/B ≃ 15% good agreement only on fast fluctuations 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  16. Scale: ~ 2 s 4.e : STAFF HBR-FGM burst mode C1 – SR2 ~50 Hz fluctuation : real signal 0.1 s  10 Hz 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012

  17. 5. Conclusion Status of dataset delivery/Delivery plan ~ OK Status of software development - DWF: finished - CWF: finished, but results under checking - CCS software almost ready - SA pipeline: to be updated with new format and new calibration tables Cross Calibration activity . Smoothed transfer function introduced (best HBR calibration) . STAFF CWF NBR - FGM one event comparison detailed . STAFF CWF NBR -FGM ten years comparison study . STAFF HBR-FGM burst mode comparaison: comparison at different time scale show limits of each instruments (1 hour, 5 mn, 30s, 2s) All this news results will be integrated in a next version of the STAFF CR, and used for the papers « ~ CLUSTER STAFF/FGM data comparaisons in the common frequency range » 16th Cross-Calibration Workshop, IRAP, Toulouse, 6-9 November 2012
