Table 6: Spatial distribution of different types of stars in the four chips of the West field. The Pre-Main Sequence stars included here are only those that can be identified individually, i.e. those with (mF675W-mF656N)>0.5.
Chip Massive stars PMS Red Clump
PC $0\pm1$ $10\pm3.2$ $8\pm2.8$
(PC $\rightarrow$WFa $0\pm1$ $48\pm15.4$ $38.7\pm13.6$)
WF2 $3\pm1.7$ $66\pm8.1$ $49\pm7$
WF3 $4\pm2$ $100\pm10$ $54\pm7.3$
WF4 $2\pm1.4$ $88\pm9.4$ $55\pm7.4$
Total $9\pm3$ $264\pm16.2$ $166\pm12.9$
(Total $\rightarrow$WFb $2.8\pm0.9$ $82.5\pm5.1$ $51.7\pm4.0$)
a Detections in the PC per unit WF area, i.e. 4.8 times larger.
b Total detections per unit WF area, i.e. 3.2 times smaller than the entire field.
