New Higher Resolution HeNeAr Atlas (1Sep93)
(from KPNO, NOAO Newsletter No. 35, 1 September 1993)

As observers push for higher resolutions and more accurate wavelength
scales to do measurements such as radial velocities, a need was felt
for a higher resolution atlas of the HeNeAr spectrum. This would enable
blends to be identified and avoided, yielding a truer estimate of the
accuracy of the wavelength fit.  HeNeAr spectra were obtained with the
KPNO 2.1-m Coude spectrograph at a dispersion of 0.35 A per pixel in the
3300 A - 5000 A region, and 0.69 A per pixel from 5000 A to 11100 A.

The new line list will be installed in the next IRAF release, V2.10.3,
in the "linelists" directory. It can also be obtained by anonymous ftp
from the NOAO machine orion. After logging in: cd kpno, get henearhres.
A copy of the wavelength plots can be obtained from the undersigned or
the KPNO observing support office.
