Caption: Figure 1.
On-sky positions of DECam field pointings for quadrant B1. The footprint consists of 29 FNs, covering approximately 30 deg2. Each field received ∼3.8 hr of integration time with individual exposures of 120 s. Field centers are defined by the R.A. and decl. of the first exposure in each long stare. Of the 29 FNs, four have been analyzed by us to date; these are shown in dark blue patches with black circles. The dashed curve indicates the solar system’s ecliptic plane.
