The Estimation of Plate Motions by Astronomical Methods

Canadian Journal of Earth Sciences, 1972
Some of the problems involved in the detection of plate motions by astronomical methods are discussed with particular reference to a Herstmonceux–Calgary cooperative program using photographic zenith tubes. Analysis of the observations obtained in 1969 and 1970 shows that several decades of continued observation may suffice with present techniques to ...

Integral methods in astronomical spectroscopy

Astrophysical Bulletin, 2010
We discuss the milestones of development of the integral methods used in the optical spectroscopy of astronomical objects. We analyze the reasons why some of these methods did not get wide practical application. We demonstrate that a combination of integral methods with multichannel detectors allow increasing the efficiency of the existing astronomical
