Medium resolution spectra

Medium resolution spectra are provided in two different resolutions and wavelength ranges (see below). FTP access to both is available at:

ftp://phoenix.astro.physik.uni-goettingen.de/MedResFITS/

In case you are interested in a medium resolution grid with another resolution and wavelength range that might be of interest for the public, let us now and we will make it available for download.

RANGE AND RESOLUTION

We support two different medium-resolution grids:

ResolutionRange
Δλ=1Å3000-10000Å
R=100003000-25000Å

For both the sampling rate is twice as high as the resolution.

PARAMETERS

The grid containts the metallicities from [Fe/H]=-2.0 to +1.0 with a step size of 0.5 plus the extra low abundances of -3.0 and -4.0.

Alpha element abundances [α/M] from -0.2 to +1.2 (Δ=0.2) are available for -3.0≤[Fe/H]≤0.0.
