... In this section, we develop a physical model of the secondary as a disk that is centrifugally supported in the radial direction and hydrostatically supported in the vertical direction. We assume that the disk is vertically isothermal and well mixed. ... where is the mean molecular mass of the gas, is the orbital period at the outer edge of the disk in years, and all of the mass of the secondary has been assumed to be concentrated near its center, so the Keplerian approximation is valid. ...

L-Narrow Cal Values . On 18 December, 2000, the L-Narrow cals were re-measured, with the results shown below. Prior to 18 December, '00, the L-narrow Cal values were assumed to be 1.85 1.91 for A B polarizations, respectively, at all frequencies. This means that gain curves obtained before 18 Dec '00 assume old cal values, and curves determined after 18 Dec '00 assume new cal values. ... lbn cal values measured 18dec00 . ... calval polA [K] . calval polB [K] . ... 1.81 . ...

Another possible way that could lead to arising diverse peculiarities in the - distribution induced by the sources evolution is connected with a possible non-monotonic character of the star formation rate in galaxies. ... The most prominent feature of the obtained theoretical - is a notable sharp increase at low count rates due to evolutionary effects. ...

Meta Index / Home Page / Description / Output The fraction of counts contained within the source region assuming a point source located at the centre of the region. The EXTENDED mode (King profile) PSF is used to calculate the fraction assuming a fixed photon energy of 1.5 keV. This is currently only implemented for circular source regions, other shapes will give the wrong factor. XMM-Newton SOC/SSC -- 2008-10-24

Comedi Documentation . ... I assume that your hardware device is in your computer, and that you know the relevant details about it, i.e., what kind of card it is, the I/O base, the IRQ, jumper settings related to input ranges, etc. To tell the comedi kernel module that you have a particular device, and some information about it, you will be running the comedi_config command. ... The overall info gives information about the device -- basically the same information as /proc/comedi. ...
