Learning outcomes

After completing the course the students should be able to:
(1) Identify and extract raw data together with the corresponding calibration frames from the ESO Science Archive that are relevant to the astrophysical science question being studied;
(2) Reduce these data using a relevant pipeline provided by ESO (use e.g. high-resolution UVES and near-infrared ISAAC spectroscopic data as examples);
(3) Carry out photometry in fully-reduced astronomical imaging observations including both relative photometry and absolute photometry with the full photometric calibration;
(4) Carry out both absolute and relative astrometry in fully-reduced astronomical imaging observations;
(5) Carry out automatic source detection, characterization and photometry in astronomical imaging observations;
(6) Produce a written course report


The course is organized by Tuorla Observatory in cooperation with the Finnish Centre for Astronomy with ESO (FINCA) and is a continuation for the 'Methods of observational astrophysics I' course which is a prerequisite for taking this course.
The course is offered for students from University of Turku, Helsinki and Oulu as well Aalto University. The course includes teaching in the form of lectures and supervised hands-on work on the data. The lectures cover the use of the ESO Science Archive and ESO data reductions pipelines (e.g. reduction and analysis of high-resolution optical spectroscopic and near-infrared spectroscopic data), the common methods for photometry and astrometry, automatic source extraction and characterization in astronomical images. Writing of successful observing proposals will also be discussed as a part of the course. The students are expected to work individually on their datasets and write-up their individual course reports at the end of the course.
