I am not sure if code will do much good here. I have included many standalone TikZ pictures but this pictures is the only one to act differently.
Here is the picture in compiled from the standalone .tex code.
Now here is the picture in the main .tex file. Notice the location of the alpha_2 and the arc in the main file which I just compiled again to verify everything was updated.
I don't know what to do about this discrepancy and how to correct it. The image is a previous run of the standalone that was incorrect. However, it refuses to update. This has never been an issue before.
In the main file, I am using the following code to include the TikZ picture.
Additionally, I have \usepackage{standalone} in the preample of the main file.
\begin{figure*}
\centering
\includestandalone{flybytrailingside}
\caption[Trailing Side Flyby]{A trailing side (or sunlit side) planetary
flyby.}
\label{trailingflyby}
\end{figure*}
For the TikZ picture, I am using the document class standalone and then drawing the picture.
The code for \alpha_2 is
\draw (3.285, 2.15) arc[radius = .125, start angle = 90, end angle = -90]
node[left, font = \tiny, inner sep = 0] {\(\alpha_2\)};

I would like to add that this problem just occurred again with a new standalone. Here is the picture compiled from the standalone:
and here is the picture in the document:
This picture was just created, compiled, then added to the main document, and compiled. The code can be found here:
