The following document lists the file abstract/PHT_CAL_P1BEAM05.abs
from catalogue VI/111.

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 wavelengths are 7.3, 11.5 and 16.0 micron.
Here: 16 micron/ 180" aperture
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
