$^{{a}}$~Heliocentric distance. $^{{b}}$~Geocentric distance. $^{{c}}$~Phase angle in degrees. $^{{d}}$~Wavelength. $^{\dag}$~The value is corrected to a monochromatic flux as defined in Campins et al. (\cite{Campins1994}). $^{\ast}$~Averages of the ISOPHOT observations. $^{\ddag}$~This is a combined value of the 04 Nov. 1990 and the 22~Mar. 1991 observations.\\
