This directory contains the data products used in the paper "An Ultraviolet Spectroscopic Atlas of Local Starbursts and Star-Forming Galaxies: the Legacy of FOS and GHRS" by C. A. Tremonti, C. Leitherer, T. M. Heckman, and D. Calzetti. (ApJ submitted, 2003) fos_ghrs_composite.txt -- a text file containing the composite spectrum shown in Figure 1. The spectra used in making the composite are in the "corrected" directory described below. column 1: rest wavelength in Angstroms column 2: average flux of the rectified corrected spectra column 3: median flux of the rectified corrected spectra In constructing the composite regions of geocoronal emission were masked in the input spectra. Note that the average spectrum contains some artifacts in the 1600 A region due to the fact that some of the input spectra are very noisy in this region (where the FOS G130H and G190H gratings overlap.) The subdirectory "observed" contains the reduced FOS and GHRS spectra. The spectra have NOT been deredshifted or corrected for Milky Way reddening and absorption. The files are in text format: column 1: observed wavelength in Angstroms column 2: observed flux in erg/s/cm^2/Angstrom column 3: rectified observed flux The subdirectory "corrected" contains spectra which have been de-redshifted, corrected for Milky Way extinction, and corrected for the Milky Way ISM absorption lines. No correction has been made for geocoronal emission or for extinction internal to the star forming region. The files are in text format: column 1: restframe wavelength in Angstroms column 2: corrected flux in ergs/s/cm^2/Angstrom column 3: rectified corrected flux
