... Previous: Implementation Design of the ASC Data Model . ... We describe a coordinate library for AXAF data analysis. The library handles transformations between celestial coordinates and instrumental (mirror, focal plane, detector pixel) coordinate systems. ... Pixlib library is intended to perform AXAF Science Center (ASC) coordinate system data analysis. ... At the present, the library affords more than 50 transformations among ~20 ASC coordinate systems. ... is zero matrix and I unit matrix. ...

... We also identified two other spectrally unique terrains, corresponding to the northern polar ice cap, and to the southern winter polar hood. Comparisons with mineral spectra indicate the possibility of different H 2O- or OH-bearing (i.e., hydroxides and/or hydrates) minerals existing both in northern Acidalia and in the nearby intermediate albedo terrain. Hydrated minerals do not appear to be spectrally important components of the southern hemisphere dark terrains imaged by HST in 1997. ...

... Matrix of Transformation | ... Every set of attitude coefficients (corresponding to a line in attitude data file) is valid for its own time interval and gives the possibility to get a matrix N of tranformation from the GSE coordinate system to the S/C coordinate system as well as a matrix M of tranformation from the S/C coordinate system to the GSE coordinate system. ... and the matrix M of transformation from the S/C to the GSE systems (the direction cosines matrix) is: . ... V GSE = M * V S/C . ...

... The Earth orientation parameters UT1 and polar motion (x pol ; y pol ) are relatґ ed with the values of UT0 and VOL obtained from the LLR analysis for a station with geocentric longitude and latitude (?; OE) by the following expression: 7 UT0 \Gamma UTC = UT1 \Gamma UTC + (x pol sin ? + y pol cos ?) tan OE 15 V OL = x pol cos ? \Gamma y pol sin ? At least four normal points for each station--reflector pair at one day were accepted for the diurnal UT0 estimations. ...

... The European HST Archive has been moved to ESA's European Space Astronomy Centre ( ESAC ), Spain, where most of ESA's Space Science Archives are located and operated from. ... The Space Telescope European Coordinating Facility (ST-ECF), jointly operated by ESA and the European Southern Observatory ( ESO ) was, until the end of 2010, the European HST science facility, supporting the European astronomy community in exploiting the research opportunities provided by the Hubble Space Telescope. ...

Paper ID No.S096.3.3 . ... This campaign combined 4 missions: Geotail, Interball Tail, IMP-8 (NASA), Wind (NASA). ... The global situation picture for the TP orbit is shown in the Fig. 1 as a satellite passage time through regions of interest of the magnetosphere. ... Correlation of the situation pictures for two orbits is helpful in choosing proper time for fulfillment of coordinated measurements in conjugate regions: plasma sheet (PS) of magnetosphere tail - auroral region (AUR). ...

Next: CONCLUSION Up: CHIRPLET TRANSFORM SUBSPACES Previous: Nondilational Chirplet Transform . Suppose we choose a windowed sinusoidal FM signal for our mother chirplet. Such a signal has a frequency that periodically rises and falls (much like the vibrato of musical instruments or the wail of a police siren). ... Figure 14 . ... Using the warbling mother chirplet, we also computed the ``dilation-dilation'' ( ) plane of the chirplet transform (Fig. 16 ) for the pendulum data. ...

First three columns show base-difference images of the evolution of the wave in 3 EUV channels (211 , 193 , 171 ) of AIA in which the wave is clearly visible. ... From our study we have quantitatively confirmed previous results that during wave passage the plasma visible in the Atmospheric Imaging Assembly (AIA) 171 channel is getting heated to higher temperatures corresponding to AIA 193 and 211 channels. ...

... The main goal here was to check whether some new bug fixes were correctly implemented (See corresponding Release Note), but mostly if P2PP correctly works with the new CCS MARCH2001 on HP-UX 11. ... Import/export OBs. ... A lot of time was spent a verifying the "synchronise" bug (item 1246). ... No critical bug found in this beta1, only 2 High and 3 Minor bugs which are to be solved AFTER MARCH2001 (next V2.1.x, if any, or V2.2). ... MINOR. ... MINOR: to be fixed in V2.2 (item 1271). ...

... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...

... Galaxies with polar rings (PRGs) are a unique class of extragalactic objects, consisting of a ring or disk of gas, stars and dust orbiting in a plane nearly perpendicular to the disk of a central galaxy. ... At present, there are only about two dozen kinematically confirmed galaxies in this PRG class, mostly from the Whitmore et al. (1990) catalogue, based on photographic images. ...

... These are plugged into plug-plate holes drilled at the predicted locations of suitable guide stars in the field of view. ... In particular, any departure from the ideal elastic curve from the tubing anchor point to the hole appears to affect the rotation angle of the plug. ...
