Query: The FRIED grid of mass loss rates for externally irradiated
  protoplanetary discs   We present an open access grid of 3930 calculations of externally evaporating
protoplanetary discs. This spans a range of disc sizes (1-400AU), disc masses,
UV field strengths (10-10$^4$G$_0$) and stellar masses (0.05-1.9M$_\odot$). The
grid is publicly available for download, and offers a means of cheaply
including external photoevaporation in disc evolutionary calculations. It can
also be queried using an online tool for quick estimates of instantaneous mass
loss rates (e.g for convenient evaluation of real observed systems). The
`FRIED' grid itself illustrates that for discs around stars $\leq0.3$M$_\odot$
external photoevaporation is effective down to small radii ($<50$AU) down to UV
fields at least as weak as 10G$_0$. At the other end of the scale, in a
$10^4$G$_0$ environment photoevaporation is effective down to 1AU even for
stellar masses at least as high as 1.9M$_\odot$. We also illustrate in which
regimes CO survives in the photoevaporative outflow for significant mass loss
rates; marking a system a good candidate to detect external photoevaporation in
weak-intermediate UV environments through sub-Keplerian rotation. Finally we
make illustrative mass loss rate estimates for discs in Taurus based on the
Guilloteau et al. (2011) star-disc parameters, finding that around half are
expected to have both significant mass loss and retain CO in the
photoevaporative outflow.
