I need help with understanding the tutorial. I am stuck on the first one. Could you please help me with how did that sheet detect “run” and “O1”? Since it will be needed to figure out the remaining sheet.
I’m not sure I fully understand your question. I will try to answer it anyway:
gwosc package, wearing the same name as the website GWOSC, speaks directly to the public database storing gravitational wave events. By using this package, we are able to retrieve gravitational wave data, in the way that is presented in Day 1 Tutorials. You can also browse the GWOSC website to get informations about observing runs and events, in a more “human-friendly” manner.
As you can see in Tuto 1.1, you can select different arguments (event, catalog, observing run, segment of time, etc.) to narrow your search, and retrieve specific events. The point in Tuto 1.1 is to show you this, and to make you use some functions with the exercises at the end.
As it is explained in the lectures, the detections of LIGO-Virgo-KAGRA are organized in “Observing Runs”. They are called O
x, and take place in time successively. For now, the run O1, O2 and O3 have been completed. You can find more information here.
If you feel stuck in this tutorial, I would suggest you to go on with the next ones, and come back to it later. You can also find the solutions to the exercises in the Thinkific Online Course, after you fill in an answer.
