[7.04] The Moments of Ca-XIX Flare Spectra as Model Discriminators

E. Newton, A.G. Emslie (UAH), J. Mariska (NRL) ()

We have measured the moments of Ca-XIX solar flare spectral profiles as observed by the Bragg Crystal Spectrometer aboard the YOHKOH spacecraft. The moments are compared to those calculated for spectra generated from numerical electron-heated model simulations, two-component Gaussian fits, and heat flux models. The comparison permits a test of various theories concerning the dynamics of the solar atmosphere during flares.}
