Notes. The columns are: (1) field name and brief description of the target; (2) effective unvignetted exposure time averaged among the 7 TMs, i.e., a sum of the exposure values in all the active cameras (not necessarily 7) divided by 7; (3) field area in degree2; (4-5) field position (J2000); (6-7) field position in galactic coordinates; (8) type of observation, including COM (commissioning), CAL (calibration), and PV (performance verification); (9) additional systematic positional uncertainties (Sect. 4.3); (10) area of selected region for the subsurvey (Sect. 4.5); (11) median value of the total Galactic absorption column density (Sect. 4.5).
