Abstract

The new visual STELLA echelle spectrograph (SES-VIS) is a new instrument for the STELLA-II telescope at the Iza~na observatory on Tenerife. Together with the original SES spectrograph - which will still be used in the near IR - and a new H&K-optimized spectrograph, which is currently in the design phase, it will change the focus of the spectroscopic observations at STELLA towards the follow up of planetary candidates detected by upcoming surveys focusing on bright targets (TESS, PLATO2). It is optimized for precise radial velocity determination and long term stability. We have developed a ZEMAX based software package to create simulated spectra, which are then extracted using our new reduction package, which is based on the PEPSI software package. The focus has been put on calibration spectra, and the full range of available calibration sources (at field, Th-Ar, and Fabry-Perot), which can be compared to actual commissioning data once they are available. Furthermore we tested for the effect of changes of the environmental parameters to the wavelength calibration precision.
