Abstract

Soft X-ray flare observations, interpreted as the emission from a single temperature plasma, frequently indicate a significant decrease in the inferred emission measure. It is shown that this effect results naturally from the isothermal assumption, and is eliminated when the preflare contribution to the total emission is removed.
