FALL 2002B special section
VLT SPECTRA REDUCTIONS:
NOTE for grism 300I data: The standard star is still the one from the first night. The red end has been cut at the sensitivity cut-off (approx. 10000 AA).
Both FITS and ASCII files are available for each SN. No smoothing has been applied.
See Chris' page here.
