Description

This repository contains six epochs of flux data for SN 2012au. Data was taken using the CCD Imaging/Spectropolarimeter (SPOL) on the 61'' Kuiper telescope, 90'' Bok telescope and 6.5 m MMT at the University of Arizona as part of the Supernova Spectropolarimetry (SNSPOL) project . Each file is the compilation of multi-day observing runs where SPOL was mounted on the same telescope and labeled accroding to the first day of observation. 

These data are presented in their original binning resolution (2.5Å or 4Å) and have not been red-shift corrected to account for the host galaxy (z=0.004483). The first column of each data file contains the corresponding wavelength of the measured value in units of Angstroms. The seocnd column of each data file contains the measured flux. The flux spectra presented are not strictly spectrophotometically calibrated and measures the total intensity (I).

Details of any adjustments made to the data for presentation in the corresponding publication can be found there.
