The accurate knowledge of the beam profiles is a prerequisite for the
calibration of extended sources of centre point source observations. It
is not possible to cover all filter/aperture combinations to assess the
beam profile shape. Based on statistics of the actual science observations
the key wavelength/aperure combinations are:

11.5 micron/52"
11.5 micron/180"

We will scan the aperture in Y and Z using a point source (star) in order
to determine the aperture profile for the two combinations
