Abstract : Once the area of a thermal region has been determined, it is possible to obtain the temperature and emission measure of the burst by examination of the flux spectrum. Such determinations have been made for three events. Temperatures in the range 2 to 6 x 10 to the 6th power K and emission measures in the area of 2.6 to 5.4 x 10 to the 49th power/cc are consistent with radio observations. Electron densities are estimated to be of the order of 1 to 8 x 10 to the 10th power electrons cc. (Author)
