This is an example of the astronomy observation time-line produced by
the scheduling software. The numbers at left and right refer to orbit
numbers since launch. Each of the four lines in a bar shows the
status of some aspect of the satellite. The top line shows the
observation status: green during observations, red during occultation
of the target, blue when the target is seen through the Earth's
atmosphere, and yellow for slews. The second line shows the receiver
mode. The third line shows the status of the two sky beams. The
fourth line shows the solar panel illumination status. In each case
different colours are used for different states.
A more detailed description of the various colours in the bars of
the timeline display is given by the
next slide.
