MINUTE EEE ANALYSIS MEETING 07/04/2021si
Update Long Distance Correlation (Paola):
- applied correction for delays of wave front propagation (assming parallelism of primaries) on coincs DeltaT for d > 5 km -> observed reduction of signal for DeltaT < 1E-4 s.
conclusions: corrections are not accurate, or the assumption on the direction correlation is wrong, or the original signal peak is due to something else (?)
- some gps problems observed in sevaral telescopes (work in progress) -> such telescopes will be excluded and the analysis will be repeated
- Comments: 1- can we trace telescope gps problems run-by-run-> via a DB?
2- can you check the event display of signal candidates?
3- what if we apply a strong cut on track parallelism in multi-track events (same telescope)?
Rate vs altitude (Francesco):
- results on rate dependence on altitude presented(from 0.6 to 2 km @Etna)
- parameterization correlation with pressure and altitude
- clear difference of altitude effect and pressure effect (wip) above 1 km
- Comments: 1- are we interested to characterize this effect independently of systematich check on the measure of rate vs latitude?
2- if yes, we explored in the past the possibility to bring a polar telescope at high altitude with a small plane (time scale not clear)
AOB:
- abstract call for SIF workshop is now open: let's start to think at possible contributions
