was more than 24 times faster in terms of seconds per template per SFT. This improvement, by more than an order of magnitude, was used to perform a deeper search over a wider parameter space than previously possible for the computational cost incurred (see target selection and search parameters below).

Target selection {#s:TS}
----------------

Unlike previous directed searches, this one targets a globular cluster. Since stars in globular clusters are very old, it is unlikely that a young neutron star will be found in such an environment. However, some neutron stars are known to be accompanied by debris disks [@Wang] and even planets [@WolszczanFrail; @Thorsett; @Sigurdsson2003]. In the densely populated core of a globular cluster, close encounters may stimulate bombardment episodes as debris orbits are destabilized, akin to cometary bombardments in our solar system when the Oort cloud is perturbed [@Sigurdsson1992]. A neutron star which has recently accreted debris could have it funneled by the magnetic field into mountains which relax on timescales of $10^{5}$–$10^{8}$ years [@Vigelius] and emit gravitational waves for that duration. Other mechanisms are likely to last a few years at most [@Haskell]. Hence an old neutron star could be a good gravitational wave source with a
