LSS of a candidate z~7 galaxy. The idea is to detect Lyman-alpha
redshifted beyond 9000 A.

Since the target is way too faint for imaging, the acquisition is
done on a reference object, then a blind offset is applied.

Two through-slit template. The first one to check the alignment of
the reference object and to apply the blind offset. The second to
check that a bright star is, indeed, in the slit, meaning that the
offset was correct. Both the reference object and the bright star
are clearly marked on the charts.

Each of the six OBs has a different dithering pattern.
