... Computing the true count rates for digital data. ... The following equation is used to find the count rate. x = ( raw counts / sample time ) . ... True count rates for digital data are corrected by using the first equation for a point source and the second for an extended source. a = ( y - pre_amp - darkrate ) / ( highvolt x pt_effic ) . ... True photocurrents (count rates for analog data) are corrected by the first equation for point sources and the second equation for extended sources. ...

2. The contour method of calculating source region shape
... Meta Index / Home Page / Description / Specifying source region shapes . When radiusstyle =`contour', the task calculates the source region shape as an elliptical locus which approximates the contour of the PSF at a given flux value. ... Clearly, in order to calculate the shape of such a flux contour, it is necessary firstly to normalize the PSF to the source brightness and secondly to determine the flux level (in `brightness' units per pixel) at which to find the contour. ...

18. Vladimir Marsakov Abstracts
... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...
