NGTS-14Ab (light green point) within the Neptunian desert, the boundary of which (as defined by Mazeh et al. 2016) is indicated with dashed blue lines. The dashed black lines indicate the region of interest identified by Szabó & Kálmán (2019). The parameters of other planets come from the NASA Exoplanet Archive, and the colour scale indicates the number of planets per grid element. The plot comprises 200 × 200 elements, uniformly spaced in log₁₀P and log₁₀R.
