Description:
Tables tablea1 to tablea6 show the absolute fluxes of the IUE standard
stars used for the derivation of the cameras Inverse Sensitivity
Curves for the IUE Final Archive. The relative fluxes of the standard
stars have been derived with the WD model, and the zero point of the
scale has been set by OAO-2 observations. These fluxes define the
absolute flux scale of IUE. Table tableb1 contains the model fluxes
of the White Dwarf G191 B2B scaled to the OAO-2 flux scale.
