Definition of connection angle #13

Open jgieseler opened 2 years ago

jgieseler commented 2 years ago

From @Laura-GitHub: For me (and in other studies I have consulted), a positive connection angle means the opposite as you have in the table. Positive CA denotes a flare source located at the western side of the spacecraft magnetic footpoint.

For example, in the following map and table (see below), MESSENGER has a negative connection angle to the flare location and EARTH has a positive connection angle. It is shown the opposite in the table. It might be possible that there are people who prefer the other way around, but I just wanted to share with you my point of view.

Also adding to this: the absolute value of the separation angle shouldn't be greater than 180 deg. In that case, it should change the sign (e.g., -90 deg instead of 270 deg).
