HELP! Jupyter Example Code Abbreviations - Brain Observatory

I need help reading the Jupyter notebook example codes on the website . I don’t know what the abbreviations stand for (Forexample: p_dg is for drifting grating stimuli, but what is the abbreviation for the natural movies/scenes and the rest of the stimuli?)?
Is there any specific folder that explains the codes and what they stand for ?
I would appreciate it if I can get a response ASAP, thank you.
