  It is important to have installed beforehand in your laptops the VO-tools to be used in the School, namely:   

  • ALADIN: Download the Aladin.jar file (Linux users only) and execute it from a terminal using “java -jar Aladin.jar”. MacOS and Windows users: download the suitable files here. Aladin is compatible with Java releases from Java release 1.7 to the last one.
  • TOPCAT: Download the topcat-full.jar file and execute it from a terminal using “java -jar topcat-full.jar”. MacOS users: download the suitable file here. TOPCAT is written in the Java language using the Java 2 Standard Edition version 8, and should run on any Java SE 8 or more recent system.
  • VOSA: Web server (you don't need to install anything). All participants must register in advance.
  • STILTS: Download the stilts.jar file and execute it from a terminal using “java -jar stilts.jar”. MacOS users may need to install JDK to be able to run STILTS.
