Notes.

(a)

Radius of a circle that includes 68% of measurements as computed from the output of edetect_stack and eposcorr via r 68 = 2.3 2 ( R A D E C _ E R R 2 + R A O F F E R R 2 + D E C O F F E R R 2 ) $ r_{68} = \sqrt{\frac{2.3}{2} (RADEC\_ERR^2+RAOFFERR^2+DECOFFERR^2)} $.

(b)

Galactic coordinates.

(c)

Number of potential matches between the Guide Star Catalogue (version: 2.4.2; Lasker et al. 2008) and EPIC source lists considered for the applied boresight correction with eposcorr.
