Notes. The final right ascensions and declinations of Pluto are corrected for differential chromatic refraction and photocenter offset. To retrieve the positions of Pluto/Charon mixed in the images, corrected by differential chromatic refraction, subtract the furnished photocenter offsets from the listed final positions. The total position errors of the (α,δ)s are computed with Eq. (8) (see text). Apparent magnitudes were computed from PSF fits with respect to the UCAC4, with errors of about 0.1 to 0.3 mag. The designation of the filters are V, R, I, and C for clear (no filter). We note that R filters used at the OPD and the 2p2 telescopes are in different systems. The telescopes are identified as Z = Zeiss, B = Boller & Chivens, P = Perkin-Elmer, and M = ESO/WFI (see also telescope details in Sect. 2). Seeing refers to the average full width at half maximum (FWHM) of the seeing disk of the stars on each frame. Here, we sampled a few of the early and last observed positions. The complete data set is available at the CDS.
