In transfer calibration of heat flux sensors, a
correction for the irradiance distribution across the
sensing area may be required when the sensing areas of
reference and test sensors are different. A method to
calculate this correction using well known equations for
the configuration factors is presented. Also, estimates
of the correction for test conditions corresponding to
the transfer calibration technique in use at the
National Institute of Standards and Technology (NIST)
