During WSR5 two injection sessions took place

Session#1

CB    injections: from GPS 847235705 to GPS 848239205
Lines injections: from GPS 847239205 to GPS 847239305
Burst injections: from GPS 847239911 to GPS 847240811

Session#2

CB    injections: from GPS 847410956 to GPS 847414456
Lines injections: from GPS 847414456 to GPS 847414556
Burst injections: from GPS 847414952 to GPS 847415852

The same signals, namely the same voltage samples as during WSR2 were injected.

Four kind of events were injected

1. BNS events, m1=1.39, m2=1.47,
   nuLow=50Hz, Nominal Distance=1.08 Mpc,
   Optimal orientation,
   Nominal SNR=(13.1, 8.66)
   
2. DFM events, a=2 b=4 g=1,
   Nominal Distance=0.17 Kpc,
   Nominal SNR=(17.3, 11.4)
   
3. Gaussian events, sigma=1ms,
   Nominal HRSS=1.48783e-20,
   Nominal SNR=(18.04, 12.51)
   
4. Cosine-Gaussian events, Q=15, f0=920,
   Nominal HRSS=3.1065e-21,
   Nominal SNR=(12.12, 7.67)
   

The two values of SNR in parentheses refer to the two injection sessions; it is remarkable the much better sensitivity we had during the first session.

The nominal SNR values were computed using the sensitivities measured (by white noise injection) immediately before the hardware injections. These sensitivities are available in the files

Distance and HRSS are nominal too, because they are based on a 13µm/Volt characteristic of the North Input actuators.
The distance for BNS and DFM events should be the same as during WSR2.

In addition to hardware injections, lines were injected during 100s at the end of each series of BNS injections.
For both instances two lines were injected

• Line1: Amplitude=4e-6V, Frequency=102Hz
• Line2: Amplitude=8e-6V, Frequency=352Hz

The frame files were produced using the vega script parseHrec.C, which in turn massages the SimEvent information produced by the h-reconstruction on the basis of the Sc_Loop_In channel.
