Zwerger Muller SN waveforms The 78 ZM waveforms differ in initial angular momentum they have (A parameter), governing degree of differential rotation initial rotational energy (B, or = Erot/Epot). A,B roughly govern how many bounce peaks are in the waveform, as seen on the left. Within each (AB) set, the adiabatic index r is varied from 1.325 to 1.28 (stiff to soft), and the peak amplidue of the wave depends strongly on this parameter, as seen in the right.

1 SineGaussians Sine Gaussians, f0 evenly spaced in logf Left: = 0.05 s, f = 6.3 Hz Middle: = 0.005 s, f = 63 Hz Right: = 10/ff0 , f ~ /ff0

LIGO-G02XXXX-00-Z AJW, Caltech, LIGO Project 2 sensitivity with PZ fit to S1H2 My reconstruction with Mikes PZ fit, on left. Right: Calibration web page. They agree very well. AND, the burst at 100 Hz injected into LDAS and passed through the response function in datacond, agrees perfectly with the matlab simulation. Confidence in use of response function!
