... To be read in conjunction with Section 7.6 of the WFPC2 Instrument Handbook , Version 4.0 Dithering is the act of displacing the telescope between observations either on integral pixel scales (to assist in removing chip blemishes such as hot pixels) or on sub-pixel scales (to improve final image resolution). ... In particular, at the time of the last writing, our experience in removing cosmic rays from singly dithered data (i.e., only one image per pointing) was quite limited. ...

Next: The Scenario Machine: Operational Up: Evolution of Magnetic Rotators Previous: Ejector-propeller hysteresis . ... The length of this segment is determined by the eccentricity. ... In this case no hysteresis occurs and transitions E -- P and the reverse take place in symmetrical points of the orbit. ... Here EP means a mixed state of the rotator at which it is in the ejector state during one part of the orbit, and in the propeller state during the rest of the orbital cycle. ...

... You are referred to Section 17.3 for extensive discussion of the many common keywords in the cg suite of software. cgspec allows you to display an image, and then overlay small plots of spectra at different locations on the image. ... In addition, you can bin the spectra up over some spatial region centred on the given locations. cgspec uses the value spectrum for the keyword type to indicate that spectra are to be extracted from that image listed in the keyword in . ... Unset for no spatial binning...

... Different sections of an image may have different exposure. ... The obvious remedy for this is to divide the input image by the exposure map before smoothing. ... If you wish to create a background map in counts per pixel from an XMM exposure in which the exposure time varies significantly between CCDs, then you will need to remultiply the the output image by the exposure map; if however you wish to create a mosaic from several different cameras or pointings, you may wish not to do so. ...

... 2007 April 22 . Smooth Sections of Asteroid Itokawa . ... Recent analyses of the border regions between smooth and rugged sections of Itokawa indicate that jostling of the asteroid might be creating segregation between large and small rocks near the surface, like the Brazil nut effect . In late 2005, Hayabusa actually touched down on one of the smooth patches, dubbed the MUSES Sea, and collected soil samples that are to be returned to Earth for analysis. ... About APOD | ...

... The greater the distance, the smaller the parallax. ... That triangle has the same proportions as the much larger triangle ABC, and therefore, if the distance B'C to the thumb is 10 times the distance A'B' between the eyes, the distance AC to the far landmark is also 10 times the distance AB. ... The most distant objects our eyes can see are the stars, and they are very far indeed: light which moves at 300,000 kilometers (186,000 miles) per second, would take years, often many years, to reach them. ...

This section of AMPLE enables one to make ephemeris calculations in various coordinate systems (spherical, rectangular) connected with different main planes (equator, ecliptic, horizon) and having origin in different points: geocenter, any point on the Earth surface, the Sun, any major planet, any minor planet. The choice of some minor planet as a center gives possibility to find approaches of the minor planet with any set of major planets and minor planets. ... equinox . 1950 2000 true . ...

Next Previous Contents . ... There are filesystems on disk partitions and other devices, and there is the filesystem as it is presented to you by a running Linux system. In Linux, you ``mount'' a disk filesystem onto the system's filesystem. ... A filesystem imposes some structure on this, and makes it look like files within directories within directories.. ... If the power cuts out at this point, the filesystem will be broken. ... Usually, the kernel mounts its root file system read-only. ...

ALMA | ... In this section, we explain why we need to correct phase fluctuations and ALMA's strategy to do this. Rapid fluctuations will be corrected with water vapour radiometers (WVRs). The Cavendish Astrophysics Group was also a leading contributor to the ALMA prototype WVRs, which were put through their paces in tests at the Submillimeter Array (SMA). ... The Cavendish Astrophysics Group in partnership with the Onsala Space Observatory built two prototype WVRs for the ALMA project. ...
