[@S5Stochastic; @S5GalacticCenter]. Most methodologically similar to this search and the S5 Cas A search was a recent search for nine supernova remnants [@S6CasAFriends], which also used fully coherent integration over observation times on the order of 10 days.

In this article, we describe a search of data from for potential young isolated neutron stars with no observed electromagnetic pulsations in the nearby ($d \approx 2.7$ kpc) globular cluster NGC 6544. Globular clusters are unlikely to contain young neutron stars, but in these dense environments older neutron stars may be subject to debris accretion (see Sec. \[s:TS\]) or other events which could render them detectable as gravitational wave sources. This particular globular cluster was chosen so that a computationally-feasible coherent search similar to [@S5CasA] could beat the age-based indirect limits on emission.

The search did not find a signal, and hence the main result is a set of upper limits on strain amplitude, fiducial ellipticity, and $r$-mode amplitude $\alpha $, similar to those presented in [@S5CasA]. An important new feature of the search described here was use of a barycentric resampling algorithm which substantially reduced computational cost, allowing a search over a larger parameter space using a longer coherence time (see
