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 (> 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 sightline. 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 iota = 8.90 +/- 0.15. The steep velocity-distance gradient along l similar to 305 degrees 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-ld = 4%).
