| Course description | This course consists of a short series of introductory lectures (7-8 lectures, 1 tutorial), the astrophysics laboratory experiments and the telescope-based group project. The initial series of lectures will introduce the students to the basics concepts of quantitative measures of light, astronomical coordinate systems, telescope design, optical/near-IR detectors and optical spectrographs. In the astrophysics laboratory the students will undertake two series of experiments. The first provides the students with practical experience of operating an optical spectrograph, including calibration, data acquisition and data analysis techniques. The second series of experiments provides the students with expertise in astronomical data analysis software through a series of experiments dealing with astrometry, photometry and spectroscopy. Finally, in the group project the students will obtain hands-on experience of obtaining and analysing their own imaging with the IfA student telescope, with the aim of determining the distance to a star cluster via the technique of main sequence fitting. |

Summary of Intended Learning Outcomes
- Set-up, calibrate and acquire data with an optical spectrograph.
- Plan and execute imaging observations of a target by
applying astronomical coordinate systems and sidereal time.
- Perform the basic tasks of CCD imaging and
spectroscopy data reduction, including absorption corrections,
astrometric calibration and aperture photometry.
- Present a complete, reproducible written or oral account of
an experiment and the conclusions drawn from it to a professional
standard, incorporating figures, tables and graphs where
appropriate.
- Identify the sources of any errors in experimental results,
quantify them and formulate approaches to control them.
- Resolve conceptual and technical difficulties by locating and
integrating relevant information from a diverse range of sources.
