We assemble a sample of 148 galaxies from the VANDELS survey at $3.35\\leq z_{\\rm spec}\\leq3.95$, selected to minimize line-of-sight contamination of their photometry. For this sample, we use ultra-deep, ground-based, $U-$band imaging and HST $V-$band imaging to robustly measure the distribution of $\\mathcal{R_{\\rm obs}}$ $=(L_{\\rm LyC}/L_{\\rm UV})_{\\rm obs}$.
