Description:
We present 8 unpublished low-resolution visual-wavelength spectra of
the Type Iax supernova 2012Z ranging from +1.8d to +248.1d relative to
B-band maximum. In addition a high-resolution spectrum is presented
obtained on -6.4d. Accompanying these data are 7 low-resolution
spectra ranging from -9.2d to +33.8d, which were previously published
by Foley et al. (2013ApJ...767...57F 2013ApJ...767...57F). The Foley et al. spectra were
provided in normalized ascii format, which we have convert to fits
format. Finally, we present the most comprehensive set of
near-infrared spectra yet obtained for a Type Ia supernova. This
includes 10 epochs ranging from -7.3d to +268.8d relative to B-band
maximum.
For spectra taken with ESO facilities a single fits file is present
for each instrumental setup, i.e., each grating has its own fits file.
For the FIRE spectra the one-dimensional spectra are stored in fits
files as 2048x3 arrays, corresponding to the wavelength, flux and
error values for each of the 2048 pixels across the detector. The
wavelength and flux are as observed.
