This will be addressed as a hands-on activity starting from real observations. We will ask the participants to install softwares on their laptop so to have the  ready to be used.

We strongly encourage you to install Virtualbox. A Virtualbox virtual machine with all the software preinstalled will be distributed the first day.
If your computer does not support Virtualbox, please install the following software:
  1. HEASoft (for tutorials on X-ray data reduction and spectral analysis): http://heasarc.gsfc.nasa.gov/docs/software/lheasoft/download.html
    - At step 2, please select at least General-Use FTOOLS, XANADU
  2. XMM : http://www.cosmos.esa.int/web/xmm-newton/download-and-install-sas
  3. Python (v. 2.7) we strongly recommend the Anaconda Python distribution, available at : https://www.continuum.io/downloads
  4. Topcat:  http://www.star.bris.ac.uk/~mbt/topcat/#install

INSTRUMENTATION: 6 hours 30 min

Emphasis on present and future, not history. Discuss the effect of charged particles when applicable. The effect of the background on the measurements will be dealt with in the Data Analysis sessions.
• X-ray telescopes (general principles and specific solutions for high resolution, high effective area, high energy, low cost, light weight) : Richard Willingale (University of Leicester) 1h30 — pdf (11.5)
• collimators-concentrators, coded masks and all sky monitors : Philippe Laurent (APC Paris) 2h — pdf (2.3 Mo), pdf (13.4 Mo)
• X-ray detectors (CCDs, DePFETs, CdTe, calorimeters) and gratings : Jean-Luc Sauvageot (AIM Saclay) 2h — pdf (26.1 Mo)
• Polarimetry : René Goosmann (Obs. Strasbourg) 1h
pdf (9.5 Mo)


On Wednesday afternoon, banquet at the Château de la Dorgonne and visit of the vineyard.

Breaks are moments of discussions whom the duration is at the discretion of the speaker and the convenience of the audience.
Lunch is scheduled at 12:00 and dinner at 19:00. Workshops will be organized in the evening discussions.
