โœฆ Synopsis

We examine the interpretation of plasma parameters derived by quantitative analysis of solar X-ray photographs obtained through broad band filters. We find some of the recent criticisms of the filter ratio method to be unfounded. Using active region and quiet Sun emission measures derived mostly from spectroscopic observations we find that effective emission measures and temperatures derived from S-054 data by filter ratio analysis are within better than 20% of the total emission measure and average temperature, respectively. The uncertainties associated with filtered flux determination are found to produce an error of about 10% in the derived effective temperature. We thus conclusively demonstrate that parameters derived from S-054 data by filter ratio analysis are representative of the observed active region and quiet Sun material.

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

A simple trap model of solar hard X-ray bursts is discussed in which nonthermal electrons trapped in a magnetic bottle precipitate into the lower chromosphere through the resonant scattering by whistlers. In -such a model, the X-ray spectra produced from trapped and precipitating electrons have 9 di

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
