A Convex Hull Peeling Depth Approach to Nonparametric Massive Multivariate Data Analysis with Applications . Abstract: We explore the convex hull peeling process to develop empirical tools for statistical inferences on multivariate massive data. ... We define the convex hull peeling depth, which enables to order multivariate data. ...

During observation the target is placed at the aperture (PC1, WF2, WFALL, etc.) specified on the Phase II proposal. ... The POS TARG special requirement can be used when a position offset is needed. ... The exact directions of the offsets are parallel to the rows and columns of the CCD on which the aperture is specified. ... This is specified in the Phase II proposal using the ORIENT special requirement. ... Figure 7.9 shows the CCD orientation and aperture locations relative to the U3 axis. ...

... Latest Supernovae . ... Sorted by Name For the years covered, 7501 supernovae and 114 extragalactic novae were reported. 378 of these supernovae were named by CBAT, 1714 were given possible supernova designations, and 5409 were not reported to CBAT. 220 supernovae were found in NGC/IC galaxies, 875 were found in named galaxies 343 objects were discovered by amateurs 4 were brighter than 13th Magnitude 208 were brighter than 16th Magnitude 1080 were brighter than 18th Magnitude 1349 ...

Next: First Catalog Sources Up: The Second EGRET Catalog Previous: Catalog Construction . ... For each observation with 3, the excess is presented as a flux with its uncertainty. ... For all except the brightest sources or those in confused regions, the statistical uncertainty is larger than any systematic uncertainties. ... The primary catalog is Table 4. ... Other names -- the source name from the first EGRET catalog ([ Fichtel et al. 1994b ]) or other gamma-ray references. ...

... While there is practically no detector noise present at energies above , X-ray data below are considerably contaminated by noise events, which become more and more dominant towards the lowest transmitted energies (Fig. ... Investigations of 40 hours of in-orbit calibration data with the filter wheel closed, taken over a period of more than two years, showed that the noise properties vary with position and energy, but are fairly stable in time for most areas on the detector. ...

... The standard science quicklook processing produces over a dozen sky maps at each downlink, and these maps are automatically searched for potential transient point sources. ... We have found that a heuristic modification of a formula derived by Li & Ma (1983) provides reasonably accurate estimates of p -values for point source detections even for very low p -value detections. ... Case 1u. The most straightforward approach uses the signal , where . ... To get a p -value, use . ...

The yellow arrow in the picture identifies the position of the black hole transient inside Centaurus A. The location of the object is coincident with gigantic dust lanes that obscure visible and X-ray light from large regions of Centaurus A. Other interesting X-ray features include the central active nucleus, a powerful jet, and a large lobe that covers most of the lower-right of the image. ...

... Miriad has a couple of tasks available for finding positions of sources (see also cgcurs in Chapter 17 ). ... It fits a 2-D parabola to the image intensities in a 3 by 3 pixel box centred on the brightest pixel in a specified region and reports the fitted location and intensity. ... Input image . ... The quality of your fit can improve significantly by selecting a snug region, and/or using the clip keyword to keep pixel values with little signal (e.g. sidelobes and noise) out of the fitting process....
