J/A+A/528/A113      Synthetic lines in the Sun   (de la Cruz Rodriguez+, 2011)

Solar velocity references from 3D HD photospheric models. de la Cruz Rodriguez J., Kiselman D., Carlsson M. <Astron. Astrophys. 528, A113 (2011)> =2011A&A...528A.113D
ADC_Keywords: Sun ; Models, atmosphere ; Spectroscopy Keywords: convection - Sun: photosphere - line: formation - radiative transfer - Sun: granulation - hydrodynamics Description: We have computed synthetic spectra from a realistic 3D numerical simulation of the solar photosphere. We provide the spatially averaged spectra for selected lines that are commonly used on solar applications. These data can be used to calibrate Doppler velocity measurements in the solar photosphere. The calculations are carried out along the solar disk from heliocentric angle mu=1.0 to mu=0.3. File Summary:

Note (1): The Doppler velocity has been computed using lambdaC as reference: Vdop=(lambda-lambdaC)*c/lambdaC. Note (2): In order to scale the µ=1.0 profile to the quiet-Sun FTS solar atlas, the intensity profile should be multiplied by Nfact. The normalization factor is fitted using the outer points of each spectrum at µ=1.0 and comparing with the same spectral region of the solar atlas.
