Targeting Flags with semaphore

This tutorial consists of an interactive Python notebook. The results are displayed here to show you what it does, but you can run it yourself if you have an account on the SciServer science platform.

This and other tutorials are available in the SciServer SDSS SAS Data Volume in the /home/idies/workspace/sdss_sas/dr19/dr19_tutorials directory. See the directions in the expandable section below.

Alternatively, you can download this tutorial notebook from GitHub.
