Determination of sky background
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 computation...
متن کاملDetermination of the Night Sky Background around the Crab pulsar using its optical pulsation
The poor angular resolution of imaging γ-ray telescopes is offset by the large reflector areas of next generation telescopes such as MAGIC (17 m diameter), which makes the study of optical emission associated with some γ-ray sources feasible. Furthermore, the extremely fast time response of photomultipliers (PMs) makes them ideal detectors for fast (subsecond) optical transients and periodic so...
متن کاملCosmic Microwave Background Anisotropy in the Cobe Dmr 4-yr Sky Maps
The COBE satellite has provided the only comprehensive multi-frequency full-sky observations of the microwave sky available today. Assessment of the observations requires a detailed likelihood analysis to extract the maximum amount of information present in the noisy data. I present a specific method for estimating the CMB anisotropy power spectrum independent of any assumptions about the under...
متن کاملAn All-sky Optical Seti Survey
We present plans for an all-sky search for pulsed optical SETI beacons at Agassiz station in Harvard, Massachusetts. We will use a 1.8 meter f/2.5 spherical “light bucket” (2-3 arcmin resolution) focused onto a multi-pixel camera consisting of sixteen 64-pixel photomultiplier tubes (with pixels measuring 1.5 arcmin on a side) in two matched focal planes. It will observe a 1. ◦6× 0 . ◦2 patch of...
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...
