Top: region selection for YSOs in the two outlying clouds. The subregion are highlighted separately: IC 2118 (blue, Witch Head Nebula) and L1616 (red). The black dots are all selected YSO candidates within the whole displayed region that pass the Gaia quality criteria within 200 pc < d < 550 pc. Only those YSOs within the circular selected regions are shown in color if they pass the proper motion selection. Bottom: YSO proper motion selection for the two outlying clouds. The colored dots indicate the proper motion selection and are the same as in the top panel. The black dots are all YSOs within the individual region selections (from top panel) but are excluded from the final samples by the proper motion cut. The gray background are all sources toward the outlying clouds that pass the quality criteria. Similar to Fig. A.3. See text for more details.
