A brief analysis of the UV data for these three objects will be presented in an Information Bulletin on Variable Stars. Observations were made with the University of Groningen 5-channel spectrophotometer on board the Astronomical Netherlands Satellite (Van Duinen et al. 1975, Astr. & Ap., 39, 159). The response functions of the channels are almost rectangular with central wawelengths and full widths (given in parentheses) at 1549(149), 1799(149), 2200(200), 2493(150), and 3294(101) Angstrom. N indicates that the optional 50 Angstrom width was used for the 1550 channel. Magnitude can be converted into absolute fluxes by m{lambda} = 0.00 for f{lambda} = 3.64 x 10**9 ergs / cm**2 s Angstrom. Chi-Chao Wu and J.A.
