- Background check: still to-do. Goal is to determine how many background slides would be affected if there were a strong gravitational wave (with a large Gamma) in the zero-lag. Note: for 4-fold coincidence, Gamma would be reduced due to time shift with LLO. But there is no H1 H2 time shift.
- Calibration: sensitivity almost certainly limited by AURIGA so it is AURIGA's calibration uncertainty that affects the ULs primarily. Does one shift the efficiency curves or just the exclusion region?
- Need a first-principles calculation of sensitivity. Should be able to compute from power spectrum what hrss is required to get a SNR 4.5 event in AURIGA. This gives an estimate of the 50% point of the optimally-oriented efficiency curve. This point will be shifted by a factor of 2/5 due to sky averaging over the AURIGA antenna pattern.
Call was interrupted by a telecon glitch. Jolien had to leave early.
