Spectroscopic analysis of the light coming from an atmosphere is a powerful tool for revealing its properties. The problem when using conventional spectroscopy for solar fluxtubes is their unresolved character: magnetic and non-magnetic regions of a plage have to be observed as a whole. With the aim of obtaining the true intensity spectrum of an

A method is presented for reconstructing the intensity profile, I, formed in the magnetic elements which have diameters smaller than the best presently achievable spatial resolution. It follows the same line as in Solanki and Stenflo (1984). As a starting point I and V of the facula and the I observed in the quiet sun are used. The filling factor

Binary models of symbiotic stars are discussed, analyzing the results of recent IR observations. It is indicated that a binary must have component masses of about 1 solar mass and a period greater than 100 days to exhibit a symbiotic spectrum, and a number of combinations of hot and cool components which would satisfy these criteria are considered
