Calculating the direction in degrees #6

I have a long lasting question about how to determine the angle from the line to the galactic center using the data. Please help!

7yl4r commented 2 years ago

It has been a very long time since I wrote this code, but it looks like the galactic lat, lon are included in the database.

So to get the angle you just use trig: angle = arctan(opposite/adjacent).

Prithwis-2023 commented 2 years ago

Yeah actually i found it and it's actually based on the galactic longitude.
