The effect of scattered light on solar intensity observations as derived from 9 May, 1970 Mercury transit
Abstract
The method for correcting observed sunspot intensities for scattered light has been tested using the transit of Mercury. It is found that the correction method of Zwaan (1965), Staveland (1970) has an uncertainty (rms value) of 0.05 times the photospheric intensity. During good observing conditions the uncertainty is 0.02 (rms value) with the scanning speed used in this study. A simpler and quicker correction method is suggested.
