The interstellar carbon abundance. II. Rho Ophiuchi and beta Scorpii.
York, D. G.; Welty, D. E.; Hobbs, L. M.
The authors describe a procedure designed to obtain increased sensitivity from high-dispersion IUE spectra by using a flat-field spectrum to remove nonrandom noise due to the response pattern of the SEC vidicon detector. Application of this procedure to spectra of ρ Oph and β1Sco near the spin-forbidden interstellar λ2325 line of C II y…
X-ray, UV, and optical observations of the dwarf nova BV Puppis.
Szkody, Paula; Howell, Steve B.; Kennicutt, Robert
The authors present quiescent state optical-to-IR photometry and IUE and optical spectroscopy as well as midstate EXOSAT and optical spectroscopy which indicate some unusual properties of this little-studied dwarf nova. The observed 2 - 6 keV X-ray flux of 4 - 5×10-12ergs cm-2sec-1 is high for a system at outburst.…
VIRIS-VAX interactive reduction of IUE spectra.
Desko, R. D.; Bord, D. J.; Davidson, J. P.
A set of computer programs, VIRIS, which has been developed to aid in the reduction of IUE spectroscopic data is described. Various methods of filtering and smoothing the IUE data are discussed, and spectral rectification routines are described. Routines which automatically locate and store the positions of absorption lines are described, as are r…
