Observation of the solar soft X-ray component; study of its relation to transient and slowly-varying phenomena observed at other wavelengths
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1969-02)
Solar X-rays from 8–12 Å have been observed with an ion chamber photometer and fluxes derived from the observations after an assumption concerning the spectral distribution. The time variation of the X-ray flux correlates ...
Asymmetries in limb darkening reanalyzed
(Kluwer Academic Publishers; Springer Science+Business Media, 1990-03)
The cause of the asymmetries in limb darkening reported by Neckel and Labs (1987) is discussed on the basis of new, stray-light-free observations, and found to be of instrumental origin.
