dc.description.abstract Andrews-Lindsay 1 is a pertinent open cluster because it may host the planetary nebula (PN) PHR 1315-6555, yet ambiguities linger concerning its fundamental parameters (&gt;50% scatter). New multiband BV JHW<sub>1&minus;4</sub> photometry for cluster and field stars, in concert with observations of recently discovered classical Cepheids, were used to constrain the reddening and velocity-distance profiles along the sightline. That analysis yielded the following parameters for the cluster: E(J &minus; H) = 0.24 &plusmn; 0.03, d = 10.0 &plusmn; 0.4 kpc (d<sub>JH</sub> = 9.9 &plusmn; 0.6 kpc, d<sub>BV</sub> = 10.1 &plusmn; 0.5 kpc), and log &tau; = 8.90 &plusmn; 0.15. The steep velocity-distance gradient along 𝓁 &sim; 305&deg; indicates that two remote objects sharing spatial and kinematic parameters (i.e., PHR 1315-6555 and Andrews-Lindsay 1) are associated, thus confirming claims that the PN is a cluster member. The new distance for PHR 1315-6555 is among the most precise established yet for a Galactic PN (&sigma;/d = 4%).
