The DECam Plane Survey [4.88 MB PDF]

Edward Schlafly

The DECam Plane Survey is a five-band optical and near-infrared survey of the southern Galactic plane with the Dark Energy Camera (DECam) at Cerro Tololo. The survey is designed to reach past the main-sequence turn-off at the distance of the Galactic center through a reddening E(B − V) of 1.5 mag. The survey has a typical single-exposure depth of 23.7, 22.8, 22.2, 21.8, and 21.0 mag in the grizY bands, with seeing around 1 arcsecond. The footprint covers the Galactic plane with |b| < 4◦, 5◦ > l > −120◦. The survey pipeline simultaneously solves for the positions and fluxes of all the sources in each image, delivering positions and fluxes of roughly two billion stars with up to 5 mmag repeatability. Most of these objects are highly reddened and deep in the Galactic disk, probing the structure and properties of the Milky Way and its interstellar medium. The full survey---fully-processed images and calibrated catalogs---is publicly available.
