J-band Spectroscopy of a z=6.5 target to hunt for the HeII line
(supposed to appear at 1.2329 micron), to determine whether this
is a PopIII object. Four almost-identical OBs using generic offset. 
I've convinced myself that the target will be in the bottom half of
the array, unaffected by the dust blob. If you find this incorrect 
during execution, please inform USG.
The acq strategy is offset from ref, but not the target will be at
the centre of the slit, but a position inbetween ref and target.
The ref stays in the slit (it might fall on the blob, that does not
matter). Please, do NOT skip acquisition, since the PI intends to
make use of the images.
