I usually prescribe 5Gy x5.
I don't prescribe to a fixed thickness but treat based on residual thickness seen on MRI using multichannel applicator.
I lesion at apex then treat upper 2-3 cm of vagina
Here is out paper describing technique and outcome in detail

In tha past we usually prescribed at 0.5 cm depth LDR or HDR biologically equivalent doses. As we have evolved to image-guided BT, I agree with @Dr. First Last's answer and @Dr. First Last's paper recommendation
