How to denote derivatives? Trailing underscore for tau derivative?

$$\frac{\mathrm d\log T}{\mathrm d\log a} = \frac{a}{T} \frac{\mathrm d T}{\mathrm d a} = \frac{a}{T} \frac{\mathrm d T}{\mathrm d a}\frac{\mathrm d T}{\mathrm d \tau} \frac{\mathrm d \tau}{\mathrm d a} = \frac{a}{T} \frac{T'}{a'}$$
