Use a numerical algorithm, the convolution network (discussed in detail below), to search for the solution that provides the desired mapping of the observed data to the desired form. ... We first made preliminary studies investigating recovery of images that have been broadened by the HST's mirror by modeling its PSF as shown in Fig. ... Our recovery procedure was applied also to spectral data, in this case to a tunable diode laser (TDL) spectrum. ...

A determination of the surface gravity and an abundance analysis of helium in a sample of 17 He-rich and 5 normal, reference stars is presented. ... The helium abundances derived from the models used are very close to 0.1 for normal, reference stars are larger for the others, clearly indicating the He-rich phenomenon in them. NLTE effects, errors on the microturbulence value or on the surface gravity do not influence the estimated helium abundances. ...

TWO IMPORTANT ISSUES FOR FFT SPECTROMETERS June 28, 2003 Carl Heiles ABSTRACT We discuss two important issues for power spectra derived from FFTing a time series. These are weighting, which eliminates spectral leakage, and \overlapping the chunks", which eliminates the nonessential increased variance that results from dividing the time series into chunks. ... We have M consecutive chunks of N-point time series, so that we have a continuous time series of length NM with no gaps. ...

... the radiative transfer equation (RTE) for the randomly-irregular magnetized plasma has been derived on the base of general grounds of the multiple scattering theory . ... Solutions of several absolute tasks of the scattering theory have been obtained (on the optical depth of the ionospheric plasma layer, on the value of radio wave anomalous attenuation, on anomalous refraction, on the backscattered signal intensity for the source being placed within a plasma layer). ...
