Cumulative coverage of all
Callisto spectrometer locations (left), assuming all instruments are working
and all antennas are tracking the sun. In fact both is not the case.
Therfore it makes sense to have some redundancy. We still have small gaps (white areas left) in winter season between 16 UT
and 20 UT and also around 1 UT again in winter-season (related to
northern side of the world). Triangles: data o.k. Stars: no data yet |
