3. Downloading tutorial datasets

All the data needed to run this tutorial are found in the tutorial’s data package.

Download the package and unpack it somewhere convenient.

cd <somewhere convenient>
tar xvf ghost_tutorial_datapkg-stdonetarget-v1.tar
bunzip2 ghost_tutorial/playdata/example*/*.bz2

The datasets are found in the subdirectory ghost_tutorial/playdata/example#, and we will work in the subdirectory named ghost_tutorial/playground.

Note

All the raw data can also be downloaded from the Gemini Observatory Archive. Using the tutorial data package is probably more convenient.
