On the Crucial Cluster Andrews-Lindsay 1 and a 4% Distance Solution for its PN

Andrews-Lindsay 1 is a pertinent open cluster granted it may host the planetary nebula PHR 1315-6555, yet ambiguities linger concerning its fundamental parameters (>50% scatter). New multiband BVJHW(1-4) 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 sight-line. That analysis yielded the following parameters for the cluster: E(J-H)=0.24±0.03, d=10.0±0.4 kpc (d(JH)=9.9±0.6 kpc, d(BV)=10.1±0.5 kpc), and log(t)=8.90±0.15. The steep velocity-distance gradient along l~305 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 (e.g., Parker et al.). The new distance for PHR 1315-6555 is among the most precise yet established for a Galactic PN (err_d=4%).
