  Given the extreme precision attainable with the Kepler Space Telescope, the
mitigation of instrumental artefacts is very important. In an earlier paper
(Murphy 2012), the characteristics of Kepler data were discussed in light of
their effect on asteroseismology. We continue this discussion now that data
processed with the new PDC-MAP pipeline are publicly available; users should
use the latest data reductions available at the Mikulski Archive for Space
Telescopes (MAST), not just for PDC, but also for improvements in the attached
meta-data. We discuss the injection of noise in the frequency range 0-24 c/d
(up to ~277 {\mu}Hz) by the PDC-LS pipeline into ~15 per cent of light-curves.
