Distribution of the 274 new YSO candidates selected in this work. Most sources were classified as new disk candidates (blue), and only few as flat-spectrum (orange) and protostar (red) candidates (see legend). The six extra PACS sources (3 P, 3 TD, Sect. 4.2), are additionally highlighted with yellow open diamonds. Sources beyond the green IRAC coverage are new VISTA/WISE or VISTA/M1 selected YSO candidates, located in areas not included in previous studies. We note that there are only five red dots visible, marking the six new protostar candidates, because two of them are lying very close to each other, so the dots are blended.
