====== Program ====== Our workshop in Heidelberg was from Monday morning the 24-th of September 2018 to Friday the 28-th at lunch time. The program includes alternating theory sessions with lectures and hands-on tutorials. On request of many we keep the program, including the slides of the lectures and tutorials online. ^ \\ ------------------ ^ Sunday 9-23-2018 \\ --------------------------- ^ Monday 9-24-2018 \\ --------------------------------- ^ Tuesday 9-25-2018 \\ --------------------------------- ^ Wednesday 9-26-2018 \\ --------------------------------- ^ Thursday 9-27-2018 \\ --------------------------------- ^ Friday 9-28-2018 \\ --------------------------------- ^ | 9:00 - 10:30 | ::: |**Lecture F. de Groot** \\ Introduction to core level spectroscopy and theoretical models.
