\caption{Effective collision strengths at $3.0\times 10^5$ K for transitions
from the ${\rm 1s}^2{\rm 2s}~^2{\rm S}_{1/2}$
ground level to the K-vacancy levels of {\rm Fe~{\sc xxiv}} showing the
effects of radiation and Auger dampings. ND: computed without damping.
RD: radiation damping is included. R+AD: radiation and Auger dampings are
included. Note: $a\pm b\equiv a\times 10^{\pm b}$.}
