The Ondřejov Echelle Spectrograph (OES) is after several upgrades a very stable high resolution spectrograph equipped with Iodine cell for high precision measurement of radial velocities, which is, however, little exploited due to the complicated data processing. The goal of the thesis is to find the optimal reduction strategy using various calibration methods and to prepare the semi-automatic pipeline based on combination of existing software modules.
The student is expected to observe with OES at Perek 2m telescope to obtain new spectra of suitable targets and calibration exposures. Basic knowledge of IRAF, C/C++, Python and essential stellar spectroscopy analysis skills are required. The important part of the thesis should be the critical report comparing the stability and performance of the OES with other similar devices in the world.
The thesis will be written in English
