Radiative Processes (year 2014-2015)
Lecturer: Alessandro Patruno & Rowin Meijerink
The “Grade” for the final exam is calculated already with the 30%-70% average rule. If the exam score was higher than the average score of your in-class tests then we have kept the exam score as the final (provisional) grade.
The retake score instead is calculated without considering the in-class tests.

On this page, you’ll find material for the course “Radiative Processes“, developed for the Bachelor in Astronomy at the Leiden University in the year 2014.
NOTE (24 November 2011): The exercises nr. 8 and their solutions had the wrong file associated. Please re-download them to be sure to have the most up-to-date version.
IMPORTANT NOTE (Wed. 10 Sept.): I’ve changed the link to the textbook above which now points to a new version of the book with several typos corrected. Please use this second version from now on.
