h1. Fourth coding sprint

The fourth coding sprint will take place at IRAP, Toulouse in the week 29 June - 3 July. We will start around noon on the first day and stop around noon on the last day so that you can travel on the same day to Toulouse (we may adapt the exact time of start on stop to your travel schedule).

h2. Collection of issues to be addressed during the sprint

I propose that the main goal of the 4th coding sprint would be to get the gammalib and ctools release 1.0 out. There are all couple of outstanding issues (see "GammaLib":https://cta-redmine.irap.omp.eu/projects/gammalib/roadmap and "ctools":https://cta-redmine.irap.omp.eu/projects/ctools/roadmap roadmaps), probably non of these issues should be blocking. We can then focus on fixing remaining issues, doing science verification and writing pending documentation. We should also start to work on the paper.

Besides this, here a list of issues that can be addressed:
* Improve binned analysis at the energy threshold (#1362)
* Implement containment_radius method for GCTAPsf classes (#1459)
* Optimise and test usage of energy resolution
* IRFs: status, limitations, roadmap
