Determination of sky background
نویسنده
چکیده
The capabilities ofmeasuring the sky background both on-board of GAIA and on-ground are discussed in relation to astrometric and photometric scientific requirements, and to onboard computing specifications. From the various ways of estimating the sky background during the data reduction it is shown that AF11 would be the more adapted, either using its edges or by LSF-fitting. A more computationally efficient way to compute the sky background on-board is proposed.

الگوریتمی جدید در تشخیص قالب و مرکزیابی دقیق ستارگان تصاویر آسمان شب
In this paper a novel night sky star pattern recognition and precise centroiding approaches are proposed. Precision and computation time of image processing algorithm paly a great role in spacecraft in which the night sky star images are utilized for attitude determination. Star pattern recognition and centroiding are the most important steps of image processing algorithm in such attitude deter...
متن کاملVariations in the sky brightness during a lunar eclipse
A total lunar eclipse is conjectured to have influence on the physical conditions of an environmental area, particularly on the brightness of the sky. The phenomenon might also be relevant on weather parameters change on Earth, such as temperature, humidity and pressure, though a straightforward correlation is not easy to establish. This work mainly aims at measuring the brightness of the sky a...
متن کاملUltraviolet Sky Radiance Distributions of Translucent Overcast Skies
The diffuse sky radiation component in the ultraviolet wavelengths is often at least 50% of the global irradiance under clear skies, and is the dominant component of ultraviolet global radiation under translucent overcast skies. The distribution of sky radiance was measured in a rural area and modeled for wavelength bands of ultraviolet-B (UVB, 280-320 nm) and ultraviolet-A (UVA, 320-400 nm). S...
متن کاملSNAP Sky Background at the North Ecliptic Pole1
I summarize the extant direct and indirect data on the sky background SNAP will see at the North Ecliptic Pole over the wavelength range 0.4 < λ < 1.7 μm. At the spatial resolution of SNAP the sky background due to stars and galaxies is resolved, so the only source considered is zodiacal light. Several models are explored to provide interpolation in wavelength between the broadband data from HS...
