A Simple Method for Correcting Spatially Resolved Solar Intensity Oscillation Observations for Variations in Scattered Light
Abstract
A measurement of the intensity distribution in an image of the solar disk will be corrupted by a spatial redistribution of the light that is caused by the Earth's atmosphere and the observing instrument. If the precise form of the spatial point spread function is known and can be modeled, then the observed image can be corrected for its effects. However, accurate modeling of the spatial point spread function, which can be considered as composed of a `blurring' component and a `scattering' component (Zwaan, 1965), is difficult and the correction for its effects is computationally expensive.
