Once downloaded, uncompress the files at any place by typing

$ tar xfvz egal.tar.gz
$ tar xfvz agn.wobble.tar.gz

You should now have a folder named 1dc in your current working directory with the following structure:

1dc/
1dc/caldb
1dc/data
1dc/models
1dc/obs

Before continuing, please set the following environment variables:

$ export CTADATA=$PWD/1dc
$ export CALDB=$CTADATA/caldb

Note

You may consider adding the CTADATA and CALDB environment variables to your .bashrc file (or equivalent) so that your analysis environment for the first CTA Data Challenge is always setup correctly.
