T he Siding Spring Survey (SSS) is a Near-Earth Object search program that utilises the 0.5-m Uppsala Schmidt Telescope at Siding Spring Observatory, N.S.W., Australia. ... The mission of the Siding Spring Survey is to contribute to the inventory of near-earth objects (NEOs), or more specifically, the potentially hazardous asteroids (PHAs) and comets (PHOs) that may pose a threat of impact and thus harm to civilization. ... Based on the CSS Mission page . ... Siding Spring Survey Main Page . ...

SAS home . ... EPIC background spectra are normally extracted from regions of the observation field-of-view, once "contamination" due to individual discrete celestial sources has been removed. ... In order to cope with this situation, blank sky event lists can be downloaded from the XMM-Newton Science Operations Center web site. ... It is in principle possible as well to extract background spectra from blank field event lists, if the spectrum accumulation regions are defined in sky coordinates. ...

... The BANNER element is used for corporate logos, navigation aids, disclaimers and other information which shouldn't be scrolled with the rest of the document. ... CLASS . ... The CLASS attribute is most commonly used to attach a different style to some element, but it is recommended that where practical class names should be picked on the basis of the element's semantics, as this will permit other uses, such as restricting search through documents by matching on element class names. ...

... There are several explanations for these X--ray quiet PMS stars. To examine the explanations, it is proper to divide the PMS stars into three groups: those bluer than R - I = 0.7, those redder than the X--ray sources (R - I > 1.25) and those with colors similar to the X--ray sources. ... A total of 26 of the non--X--ray detected PMS candidates had spectra taken. ... Between V=14 and V=16, I find 25 stars which are X--ray sources and estimate 19 non--X--ray PMS stars. ...

Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... NICMOSlook and Calnic-C are two programs that were designed to take advantage of the fact that the NICMOS grism mode typically consists of taking both a direct and a grism image. ...

... Coronographic images were made of a 1.7 x 1.7 arcsecond area around Proxima Centauri in July and October 1996 using the FOS Large Barred Aperture. A faint feature was identified whch changed position between the two visits, relative to the FOS aperture and relative to the sky. ... The feature can be modeled as a companion 7 magnitudes fainter than Proxima (V=11.2) and about 0.5 AU from the star (H.M. Hart, A.B. Schultz, F.C. Hamilton, M. Kochte (CSC), C.D. Keyes (AURA)) . ...

... The vast quantities of data produced by modern radio telescopes have outstripped conventional visualization techniques available to astronomers. ... While visualization techniques in other areas find some application in astronomy, problems peculiar to the field require new techniques, such as methods for identifying three-dimensional regions. ... By presenting data three dimensionally, the astronomer may identify structure in the data which is not obvious when using conventional tools. ...
