Abstract:
We present 32 epochs of optical (3300-9700Å) spectrophotometric
observations of the nearby quintessential "normal" type Ia supernova
(SN Ia) SN 2011fe in the galaxy M101, extending from -15 to +97d with
respect to B-band maximum, obtained by the Nearby Supernova Factory
collaboration.
SN 2011fe is the closest (µ=29.04) and brightest (Bmax=9.94mag)
SN Ia observed since the advent of modern large scale programs for the
intensive periodic followup of supernovae. Both synthetic light curve
measurements and spectral feature analysis attest to the normality of
SN 2011fe. There is very little evidence for reddening in its host
galaxy.
The homogeneous calibration, intensive time sampling, and high
signal-to-noise ratio of the data set make it unique. Thus it is ideal
for studying the physics of SN Ia explosions in detail, and for
furthering the use of SNe Ia as standardizable candles for cosmology.
Description:
The data were obtained using SNIFS (SuperNova Integral Field
Spectrograph) on the University of Hawaii (UH) 2.2m telescope.
For observational conditions of each individual exposure, please
refer to the FITS header.

Note (1): The 1D FITS files contain the flux in the primary extension
and the variance as a separate extension. The spectra have not been
redshift-corrected, but have been corrected for Milky Way extinction as
described in the paper. The FLUXERR keyword represents the (achromatic)
absolute flux calibration accuracy [mag] as estimated by the calibration
pipeline, and should be added to the error of any synthetic magnitudes
(not colors) computed using the spectra.
The filename notation is 11fe[PM]xxx.*, where [PM] stands for Plus or
Minus and xxx is the phase of observation, in days relative to B-band
maximum, times 10, eg.:
11feM083.fit = - 8.3 d
11feP217.fit = +21.7 d
Some or all of the data included here will eventually be superseded by
improved reductions in a subsequent SNfactory data release. For that
reason, we suggest that users occasionally confirm that they have the
most recent version of the data by checking the SNfactory website. We
would also recommend that people looking to get the data for the first
time get it from the website directly.

Rui Pereira,
Please do not publicly re-host the data on the web somewhere else
without checking with us first. We would like it to be clear to
everyone the authoritative reductions are always available at the
SNfactory project web site.
