41. Accuracy of World positional CCD observations of the numbered minor planets
... Our scientific interest is an accuracy of asteroid CCD observations obtained by amateurs and professional astronomers all over in the World. ... These data help us to analyse an accuracy of real CCD positions in the MPC Database. ... Do you test your observations of the small Solar System bodies permanently before sending them to the International Minor Planets' Center? ... Do you know a real accuracy of your positional CCD-observations in comparison with the other observatories' one ? ...

ATMoB "Open Cluster Observing Award " Guidelines Purpose: To promote observing among the membership of the Amateur Telescope Makers of Boston through participation in the Open Clusters Observing Awards program. Introduction: This awards program is oriented towards visually observing open clusters above magnitude 9.9. ... It turns out that a very unprejudiced and convenient method to dermine the limiting magnitude is to count the number of visible stars in certain areas on the sky. ...

... Virtually all detectors and telesco pes are sensitive to only a particular range of frequencies or wavelengths. ... Flux per unit wavelength or frequency So in practice, when we measure how much radiation we receive from some object, we usually mean the energy at some particular frequency, not the integral of the energy over all frequencies (which would be the bolometric brightness). ... But imaging data at UV, optical and IR wavelengths often uses a different approach: broad-band imaging. ...

45. The COOC Criterion (Criterion of Observations versus Calculations)
... In order to compare the number of different evolutionary stages obtained and X-ray luminosity of the chosen X-ray sources with the observed galactic values we use the sum of C/O+O/C , where C and O are the calculated and observed values of a given binary type, respectively. If we make comparison for a number of different binary species (for example, we compare the number of CV, number of X-ray pulsars, total X-ray luminosity of LMXB, etc.), we write this criterion in the form: . ...

57. Starlight Polarization
Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...
