Integral methods in astronomical spectroscopy
Astrophysical Bulletin, 2010We 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

Determination of the Astronomical Unit by the Dynamical Method
Nature, 1967THE dynamical method of determining the astronomical unit is based on a relation between the astronomical unit A expressed in km and the ratio m of the mass of the Earth–Moon system to the solar mass. According to this relation m A3 equals a constant which is known with sufficient accuracy for all practical purposes.

An Innovative Method for the Alignment of Astronomical Telescopes
Publications of the Astronomical Society of the Pacific, 2001An algorithm is presented that accomplishes the optical alignment of Cassegrain and Ritchey‐Chretien astronomical telescopes. The algorithm does an iterative comparison and minimization of the error between the ideal pattern of the transverse aberration, TA, and the actual or measured pattern of the TA of the telescope.

On the astronomical method of tracking satellites
Chinese Astronomy, 1980Abstract In this paper we use the theory of multivariate error analysis to find the expression for the covariance matrix of satellite positions attained by the astronomical method. The dependence of the positional accuracy of the target to the reference stars and on its position within an interpolated segment is discussed and explicit formulae are ...

Rapid methods for determining astronomical azimuths
Eos, Transactions American Geophysical Union, 1944Astronomical computations for position or azimuth are not difficult for the astronomer or mathematician, even though such computations may be time‐consuming. In the past few years, however, there has been a general trend toward the simplification of problems involving astronomy.

The Estimation of Plate Motions by Astronomical Methods
Canadian Journal of Earth Sciences, 1972Some 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 ...

A Subpixel Deconvolution Method for Astronomical Images
1991We present results from the use of an image deconvolution method for achieving subpixel resolution in certain data regimes. Restorations are performed using a shell which utilizes the Gull-Skilling MEMSYS-3 package. We have performed extensive tests using the method and have determined general limits of its applicability and resolving power. We present

Geometric method to measure astigmatism aberration at astronomical telescopes
Applied Optics, 2007A simple geometrical method to measure the aberration of astigmatism present in the wavefront that emerges from a telescope is presented. The method is based on the analysis of the external contour of the image of a slightly defocused star. An expression elliptical edge is obtained, which links the rms value of Z22 to the geometric parameters of the ...

Automatic processing method for astronomical CCD images
SPIE Proceedings, 2002Since several hundreds of CCD images are obtained with the CCD camera in the Lower Latitude Meridian Circle (LLMC) every observational night, it is essential to adopt an automatic processing method to find the initial position of each object in these images, to center the object detected and to calculate its magnitude.
