This paper discusses the methods used to analyse and interpret X-ray filtergrams obtained by solar soft X-ray telescopes such as the S-056 Skylab instrument. First, an appropriate definition of the line-of-sight emission measure ~L(T) is developed, and it is shown how the X-ray data may be analysed
In the light of a recent discussion by Gerassimenko and Nolte (1978) we re-examine the use of the 'filter ratio method' for determining the thermodynamic parameters of coronal plasmas. We conclude that the method gives reliable results only when the observed plasma is nearly isothermal and that pres
