Workshop Preparation

If you are planning on attending an upcoming workshop, please read the following preparation information.


You are expected to bring a personal laptop to the workshop. This allows you to learn CIAO in the environment you will regularly use, and makes it easy to bring all your workshop hands-on projects back with you.

Your laptop must be able to run CIAO! The supported platforms are available on the Platform Support page.

CIAO/Chandra Data questions

If you have already worked with CIAO and/or Chandra data and have questions you would like to ask, we suggest to submit them in advance to CXC Helpdesk. Mention that you are a CIAO workshop attendee, and we will make sure that an answer is ready for you at the time of the workshop.

Suggested pre-workshop reading

If you don't have CIAO available, try installing the software. There are step-by-step instructions available in the Installing CIAO thread.

We also suggest reading and/or trying some of the introductory threads found on the Introductory Threads page.

Working on your own Chandra data:

We encourage you to download your favorite observation from the Chandra Data Archive. If you have no preference, download some of the datasets used in the CIAO threads:
