| The DECam Plane Survey: Optical photometry of two billion objects in the southern Galactic plane |
| This table contains the band-merged catalogue from DECaPS Schlafly et al. 2018: http://adsabs.harvard.edu/abs/2018ApJS..234...39S The DECam Plane Survey is a five-band optical and near-infrared survey of the southern Galactic plane with the Dark Energy Camera at Cerro Tololo. The survey is designed to reach past the main-sequence turn-off of old populations at the distance of the Galactic center through a reddening E (B - V ) of 1.5 mag. Typical single- exposure depths are 23.7, 22.8, 22.3, 21.9, and 21.0 mag (AB) in the grizY bands, with seeing around 1". The footprint covers the Galactic plane with ∣b∣ < 4deg, 5deg > l > -120deg.
