Abstract

The Echelle spectrograph FOCES is currently located at the laboratories of Munich University Observatories under pressure and temperature stabilized conditions. It is being used as a test bed for a number of different stability issues related to high precision radial velocity spectroscopy. We utilize FOCES to study spectrograph stability, illumination stability and fiber transport stability. With this work we continue the series of papers that present our efforts to obtain temperature and pressure stabilization in the spectrograph environment. In particular we present first optical measurement results and compare them to simulations previously published. We show the movement of the image on the CCD with changes of pressure and temperature and the stability of the spot positions in the stabilized system using measurements done by a ThAr gas discharge source.
