The colour of the Deep ROSAT X-ray sky fluctuations
We have carried out a fluctuation analysis in four bands (R4, R5, R6 and R7 corresponding to 0.44-1.01 keV, 0.56-1.21 keV, 0.73-1.56 keV and to 1.05-2.04 keV respectively) of two very deep ROSAT PSPC observations in directions where the galactic HI column is minimal. This has enabled us to study the average spectrum of the sources contributing to 0.5-2 keV fluxes ∼ 10erg cm s . The best fit spe...
متن کاملA Fast Display Method of Sky Colour Using Basis Functions
Computer graphics recently have began being used for visual environmental assessment or architectural designs. Displaying the sky as a background is indispensable in generating photorealistic images for such applications. In this paper, we propose a fast display method of the sky color by expressing the intensity distribution of the sky using basis functions, even if the sun position and/or the...
متن کاملruby of the sky
in a profoundly impressive verse in shahnameh, sky is likened to red ruby. the present paper is attempted to probe into the background of the conventional belief regarding the relationship between sky and stone, for the semantic structure of the verse is composed in such a way that it is not possible to consider this relationship as being a conceptualistic viewpoint so that one may establish so...
متن کاملCombination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...
متن کاملSky Quality Meter measurements in a colour changing world
The Sky Quality Meter (SQM) has become the most common device to track the evolution of the brightness of the sky from polluted regions to first class astronomical observatories. A vast database of SQM measurements already exists for many places in the world. Unfortunately, the SQM operates over a wide spectral band and its spectral response interacts with the skys spectrum in a complex manner....
