This tar file contains optical and IR spectra of SN 1999ee.
In each of these files, column 1 is the rest wavelength in Ansgtroms
and column 2 is the flux in units of F_lambda (ergs/sec/cm**2/A),
corrected for Galactic and host-galaxy dust absorption.
The files are named after the UT date of observation.

The optical spectra are called sn99ee.opt*. They were grey-shifted
in flux in order to match the V magnitude of the SN.

The IR spectra are called sn99ee.ir*. They were greyshifted in flux
relative to the optical spectrum nearest in time, using the small
overlap wavelength region around 10000 A.

I combined all of the above into the following optical+IR spectra:

sn99ee.18oct99.a0.z0.a0.txt 

Because there was not always overlap between the H and K spectra
and the Z and J spectra, I could not match the H and K fluxes
on 02nov99, 09oct99, 18nov99, 19oct99, 28nov99, and 18oct99.
However, the weather was photometric on these nights so I think
that overall these fluxes are accurate to 20%. In the other cases
I am confident that the fluxes are good to 10%.

All the above spectra were corrected for 
Galactic extinction amounting to E(B-V)=0.02, 
redshift corrected using the heliocentric redshift of 3498 km/s , 
and corrected for dust in the host galaxy amounting to E(B-V)=0.3. 

More information: The SN reached maximum on JD 2451469.0 (1999 Oct 17.5 UT)
and had Dm15(B)=0.98.

Plots: They show the optical, IR spectra, and combined spectra in
postscript form.
