Notes. The listed quantities are: HEALPix indexing, coordinates for the field centers in equatorial, Galactic, and ecliptic reference frames, and the number of targets falling into the P1-P2-P4-P5 categories. The P1-P2-P4-P5 requirements are formally specified for the sum of the LOP fields; the quantity reported in the “notes” column is just half of that value (See Sect. 2.2 for more details).
