... Among the objectives of Principal Components Analysis are the following. dimensionality reduction; љ . the determining of linear combinations of variables; љ . ... identification of groups of objects or of outliers. ... Finding a set of principal axes allows the objects to be adequately characterised on a smaller number of (artificial) variables. ... Reduction of dimensionality is practicable if the first new axes account for approximately 75 % or more of the variance. ...

... The HST uses an onboard model of its orbit to perform in real-time various control functions relating to spacecraft operations and observation support. ... New coefficients for the ephemeris are updated every other day, and are archived as FITS keywords for each HST observation data set. Using these coefficients,an observer can perform a variety of calibration and characterization calculations relating to the orbital position and velocity of the telescope. ...

... Polar Cap Potential . ... The solar wind propagation delay time calculation used here is conceptually similar to the T(IMF) calculation in Kelly, et al. ... The older continuous data are from key parameter data files. ... Note: Very high values of Solar Wind Speed, Solar Wind Pressure, IMF Magnitude and Bz, and Polar Cap Potential are likely indications that WIND has reentered the Earth's magnetosphere; such data is not indicative of solar wind conditions or impending severe geomagnetic disruption. ...

ST ScI Preprint #1380 . Authors: A. A. Suchkov, 1 M. McMaster 1 We find evidence for the presence of a population of numerous binaries with comparably bright components (C-binaries) among HIPPARCOS F stars that are flagged in the HIPPARCOS catalogue as single. ... The criterion is based on comparison of absolute magnitude M V obtained from the HIPPARCOS parallax and Johnson V magnitude with absolute magnitude derived from the dereddened uvby luminosity index c 0 , M c 0 . ...
