Template Spectra

Pickles Stellar Spectral Flux Library

The UVKLIB spectral library (A.J. Pickles, PASP 110, 863, 1998) provides spectra for different spectral types in the domain 115nm - 2500nm with a step size of 0.5 nm.

Kurucz Model Spectra

Kurucz model spectra cover the range 100nm - 1100nm with a step size of 0.1 nm.

Planetary nebula

The planetary nebula spectrum corresponds to NGC 7009, Emiss. lines from Hyung & Aller, 1995; Barker, 1983. Produced by J. R. Walsh (Space Telescope European Coordinating Facility), May 1996. This spectrum cover the range 100nm - 1100nm

HII Region (Orion)

Orion nebula is a composite spectrum. UV lines, optical lines, nebular continuum plus hot star model atmospheres. Produced by J. R. Walsh (Space Telescope European Coordinating Facility), May 1996. This spectrum covers the range 100nm - 1100nm.

Kinney-Calzetti Spectral Atlas of Galaxies

The Kinney-Calzetti atlas contains spectral templates of galaxies covering the ultraviolet to near-infrared spectral range, i.e. from 120nm up to around 993nm. The following list of templates have been selected from the atlas.

MARCS spectra

The MARCS set of spectra was made using the one-dimensional, hydrostatic, plane-parallel LTE model atmospheres (https://marcs.astro.uu.se) for stars in the temperature range 3,000 to 8,000 K and log g = 3 to 5. Only models with solar metallicity and microturbulence = 2 km/s were considered.

They were used as input to the Spectrum stellar spectral synthesis program to compute flux calibrated spectra, in the wavelength range from 3,00 to 20,000 nm, with a resolution of 0.001 nm.

These spectra were then rebinned logarithmically to a final resolution of 200,000 using SpectRes. It is a pleasure to thank Dr. Richard O. Gray from the Appalachian State University for adapting his code and providing the necessary line lists.
