Here is a plot of the data obtained at keck (red), subaru(blue), vlt(green). The Keck and Subaru data agree
very well, but the VLT data have to be subtracted by a constant and multiplied by a constant factor.
This figure shows that the red edge of the spectra are not due entirely to calibration effect, but
rather is a strong evidence that the peak is indeed quite narrow. If this is the case, it rules out
the peak as been the Ca II peak, and would put the supernovae at z = 1.5.
Cheers,
Lifan and Greg
