Let’s start PyRAF and get some basic configuration done.

First, we need to activate the anaconda environment that holds IRAF, PyRAF, and the Gemini software. Then we can go to our work directory, launch the image display ds9 and launch the PyRAF session. This is all done from the bash shell.

/bin/bash -l

source activate geminiconda
cd /your/work/directory

ds9&
pyraf

Now we are in the PyRAF session. We need to load the gemini package and the gmos package. Then the standard image buffer needs to be set. (If you forget, gdisplay will remind you. If you followed the installation instructions, IRAF should already be aware of pyfu and lacos_spec.cl thanks to the definitions that were added to the loginuser.cl file.
