The flux densities quoted in the ISOPHOT AAR results have been derived
from the detector in-band powers assuming an energy distribution of
the source which is constant in the flux per logarithmic frequency
interval; i.e., the flux density with frequency
goes as
. This is
the same convention as used for IRAS data.
In order to derive the flux density for any other spectral energy distribution (SED) a `colour correction' must be applied to the background subtracted source flux density in the following way:
![]() |
(C.1) |
where:
= flux density for applied SED
= quoted flux density in AAR
= tabulated colour correction factor for applied SED
Tabulated colour correction factors are available for
