Abstract

The absolute (photometric) calibration of the Halley Multicolour Camera (HMC) is described. HMC, prior to its observations of comet Halley on 13–14 Mar. 1986, imaged several stars and planets. The fluxes from the objects and the observed signals in digital units (DU) have been computed. A spectrally independent measure of the response of the instrument has been determined. This value has been used to derive conversion factors from DU to mW m⁻² sr⁻¹ and reflectivities for all HMC configurations.
