Methods of observations and astrophysical data reduction: Spectroscopy.
Description of the 2-m telescope and spectrograph, selection of targets.
Emission and absorption spectra. Calibration (comparison spectrum, darkframe,
flatfield). Reduction of measured spectra, spectral line identification, radial
velocities determination.
Tasks are processed via remote access to the 2-m telescope or directly in
the dome of AI ASCR in Ondrejov.

The lecture course is closed by the obtaining the course-credits.
The spectroscopic observations are at the 2m telescope at the Ondřejov observatory under the supervision of one of the lecturers. Students have to obtain data and reduce them using the program IRAF (available at the server sirrah of the Astronomical Institute MFF UK). After the reduction, the normalisation of the spectra and identification of the most intense lines is requested. A report from the observation, about the instrument, data reduction, line identification, and a small recherche about an observed object is the requirement for the obtaining of credits.
A small practical course about the data reduction in IRAF is at the beginning of the semester.
Note, considering the weather in the central Europe, we highly recommend to do not wait until the end of the semester. Last update: Korčáková Daniela, doc. Mgr., Ph.D. (10.06.2019)

Methods of observations and astrophysical data reduction: Spectroscopy.
Program and objectives: 1. Description of the 2-m telescope and slit spectrograph, dispersion. 2. Selection of targets according to the scientific program: emission stars, symbitic stars, spectroscopic and eclipsing binaries. Emission and absorption spectra. Balmer series. 3. Calibration frames (comparison spectrum Th-Ar, darkframe, flatfield). 4. Reduction of measured spectra, spectral line identification, radial velocities determination.
Tasks are processed via remote access to the 2-m telescope or directly in the dome of AI ASCR in Ondrejov. Last update: T_AUUK (26.03.2015)
