What is the Hot Spot :
The Hot Spot is the location that is defined as the position of the
star when the wavefront sensor is "on-axis". This has to coincide with
the telescope pointing axis so that when a star is acquired, it will be
aligned with the wavefront sensor. Usually the hot spot is defined to be
a little bit off axis because the center of KIR has a row and a column
that are less than perfect. Note that unless the observer requires it,
this should only be done on the first night of an AOB run.
After the OA has set up on their meridian/equator star, have them go
to a guide star:
