bad spacing between macro and real rendering

Question

Here is a capture of the current rendering I get :

I am obliged to set a "\," after the GC$_{\text{ph}}$ and WL to have a little spacing after these symbol to not interfer with classical text, that is to say :

\newcommand{\GCp}{GC$_{\text{ph}}$\,}
\newcommand{\WL}{WL\,}

and the Latex source :

Here after a triplot showing the 2D joint distribution with individually the \GCp and \WL probes and their simple combination.

As you can see, this is not symmetric and even I put "\," on each side in \newcommand, this is not pretty.

I am on overleaf.

If someone could tell me how to fix this ?

Answer 1

I did not understand why you want to type \WL to print "WL"! Simply type "WL". For the other one, take \newcommand{\GCp}{$ \text{GC}_{\text{ph}} $~}
