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. More information here.
  

• TOPCAT: Download the topcat-full.jar file and execute it from a terminal using “java -jar topcat-full.jar” (Linux and Windows users. For windows users, double-click on the topcat-full.jar file may also work ). 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. See the documentation here.
  

• VOSA: Web server (you don't need to install anything). All participants must register in advance.
  

• STILTS: Download the stilts.jar file. MacOS users may need to install JDK to be able to run STILTS. See the documentation here.
  

• Python: The tutorial #4 is designed to be followed using the web service Google Colab, an easy-to-use Jupyter Notebook environment hosted in Google's cloud (no Python installation required in local computer). Requirements: to have a Google account and download and extract the files included in VOpython_data.zip. Please, do it before the tutorial.

  For the participants who would like to follow the tutorial in their own Python & Jupyter Notebook environment, the requirements_oct22.txt file includes the Python packages that need to be installed before the tutorial. Using pip, you can install the packages using the command "pip install -r requirements.txt" (when the packages are installed, please check the import cell of the notebook is working). If you experience problems when installing the Python packages in your own environment, please, contact pmas@cab.inta-csic.es.
  

 For a correct developement of the school, we encourage all participants to test Aladin, TOPCAT and STILTS following this short video and using this file.
