... The fitting procedure will only converge to a unique solution if the components are linearly independent. ... The task calculates for each pair of component images and fails with an error if any is greater than 0.99. ... Hence components may be linearly independent in masked pixels yet still fail the test within the task. ... Finally, since the Poisson image values are necessarily all , negative values are not allowed in the model components. ...

The wave complex KEM-3 is designed to measure the parameters of electromagnetic waves in the VLF and ULF ranges. ... The electric antenna is a 1.6 m long dipole made up by two spherical carbon EDS detectors each with a preamplifier. ... The same detector is also used for the VLF device. ... 1. component Ex: 0.1 Hz - 400 kHz; 5*10E(-8)HzE(-1/2) (2 kHz). 2. component Bx: 1.0 kHz - 50 kHz; 10E(-5) nT*HzE(-1/2) (2 kHz). 3. components Bx,y,z: 1.0 Hz - 2 kHz; 3*10E(-5) nT*HzE(-1/2) (100 Hz). ...

... 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. ...

spaceweb@oulu.fi - last update: 13 September 1998, 1130 UT (RR) . Ground based magnetometer measurements are used to derive several indices that describe magnetic activity in the Earth 's environment. aa , AE , Ak(Hel) , Kp , Dst , PC , MT . ... AE index is an auroral electrojet index obtained from a number (usually greater than 10) of stations distributed in local time in the latitude region that is typical of the northern hemisphere auroral zone (Davis and Sugiura, 1966). ...

... Archives . ... The PCA and ICA is used for separating mixed components with some assumptions. ... The need of source separation methods in astronomy has led various adaptations of decomposition methods available. ... I rarely come up with a paper which gathered and summarized component separation methods applicable to astronomical data. In that regards, the following paper seems useful to overview methods of reducing dimensionality for astronomers. [arxiv:0805.0269] . ... Chandra Blog . ...

We present results of new Monte Carlo calculations made with the DIRTY code of radiative transfer of stellar and scattered radiation for a dusty giant late-type galaxy like the Milky Way, which illustrate the effect of the attenuation of stellar light by internal dust on the integrated photometry of the individual bulge and disk components. ... In addition, we find that the structure of the dusty ISM affects more sensitively the observed magnitudes than the observed colors of both bulge and disk. ...

HD 98088 is a synchronised, double-lined spectroscopic binary system with a magnetic Ap primary component and an Am secondary component. ... The magnetic field in the primary is predominantly dipolar, with the positive pole oriented approximately towards the secondary. ...

Next: Star Formation Rate and Up: No Title Previous: Calculation of Evolutionary Tracks . To start calculations, we choose the distributions of the initial binary parameters: the mass of the primary ZAMS component, , binary mass ratio, , orbital separation a . ... whereas the mass ratio distribution is not. ... The zero assumption often made is that the mass ratio distribution has a flat shape, that is binaries with a high mass ratio occur as frequently as those with equal masses. ...
