EXPLANATION
The sence is complex. A bright source at the very edge of the field
was correctly centroided in ACQ, moved to the SS and then to the slit.
It's likely that the science target was lost, but observer should
double check. (Note that the source closest to the ACQ aim point was
only the 3rd brightest thing in the field).
