Spitzer IRAC 3.6 μm finding charts with the APEX/SABOCA detections, except for SB14 (IRAC 8 μm image). North is up and east to the left. The green crosses represent the coordinates of the peak emission of the APEX/SABOCA detections. The white contours represent the APEX/SABOCA emission at 2.5, 3, 4 and 5σ level. The infrared counterparts within a radius of 5.̋3 (half of the APEX/SABOCA beam) are represented by yellow crosses. If previously discussed by BGH16, they are named with the APEX/LABOCA designation. If not, they are named with low-case letters. The magenta circles represent WISE detections, the cyan diamonds represent the position of the APEX/LABOCA cores peak intensity, and the blue circles indicate AKARI detections. The orange square represents a Planck detection (see text).
