MAST Composite Quasar Spectrum

This is a mean quasar spectrum, between 350 and 3000 Å, constructed from 2 84 FOS obser vations of 101 quasars with redshifts z > 0.33, as described in Zheng, W., et al. 1997. This reduced archival data is made available courtesy of Dr. Wei Zheng.

The spectrum is available as a flat ASCII file:

• Uncompressed (409.96 kbytes)

• Unix compressed (93.087 kbytes)

• gzip compressed (78.277 kbytes)

The table columns are:

• Rest wavelength (Å)
• Relative flux F()
• Error
• RMS

This is a mean quasar spectrum from 630 A to 1156 A, constructed from 128 FUSE observations of 85 AGNs with redshifts z < 0.67, as described in Scott et al. 2004 in the 1 Nov 2004 issue of The Astrophysical Journal.
