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.

Textbook: Radiative Processes in High Energy Astrophysics

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.
