✦ Synopsis

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 presently available data do not demonstrate that active region plasmas generally meet this condition.

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

The erroneous electron energy loss rate of Brown et al. (1983), used in their interpretation of multi-spacecraft hard X-ray observations, is corrected. The inference of column depth in the occulted source is repeated, mostly with only slightly different results. Additionally, it is pointed out that
