UBV magnitude differences in visual binaries are presented and their accuracy is discussed. Typical observed image profiles of double stars, including sample profiles of Antares, are shown. This contribution will appear jointly with the earlier one (p. 20) in Lowell Obs. Bull., No. 154. The work has been supported by NSF Grant GP-6983.
