Minimum masses of the planet(s) predicted to exist in our debris disc systems, for three different scenarios: a single planet sculpts the inner edge of the disc (top plot), multiple planets sculpt the inner edge of the disc (middle), or a single planet stirs the disc (bottom). The solid bars show predicted planet parameters in all of our systems, and the hatched bars show only systems where the disc parameters come from resolved images (ALMA or Herschel); the results for resolved and unresolved discs are similar for sculpting planets (top two plots) but differ for stirring planets because the results for unresolved discs are conservative lower bounds (Sect. 4.2.1). For the multi-planet scenario (middle plot), we note that the plot shows the mass of each individual planet.
