These images, taken two weeks apart, show the two hemispheres of Ceres and provide the best ground-based observations of the dwarf planet ever. They were taken using the SPHERE instrument on ESO's Very Large Telescope and form part of an effort undertaken since mid-July 2015 to compose a polarimetric map of the object's surface. ...

... The active time at each angular bin is the sum over frames of the active time contributions from all CCD pixels, within the node-specific telemetry window, which overlap the surface of the bin. ... The active time, per frame, of a normal pixel is the full frame integration time multiplied by the node-specific fractional exposure; bad pixels contribute no active time. ... If an event is rejected for this reason only, then its pixels remain normal in the exposure map. ...
