The models provided are: . abs - absorption of x-rays by neutral gas with solar abundances. parameter 1 = . ... parameter 2 = . ... normalization - logarithmic value of the flux density at 1 keV in units of keV cm -2 s -1 keV -1 . ... normalization - logarithmic value of the normalization of the gaussian in units of keV cm -2 s -1 . ... absorption ( params )* model ( params ) . ... A single value for the normalization (i.e., fixed normalization) will force the program to use that value. ...

Next: VLAUSERN Up: Details of SCHED Parameters Previous: VLARFANT Contents . All of the VLA parameters are, at temporarily, out of use. The old VLA system has been turned off and the EVLA is entirely different. For now, the EVLA is being treated more like a normal station. VLATYPE specifies the type of the observation for the VLA observe file. ... Options: 'VLBI' - VLBI observation. CONTINUUM' - normal VLA continuum observation. LINE' - VLA spectral line observation. ...

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. ...

The principal designation is the name, amongst the different possible names, chosen to identify the object because it is considered as the most reliable to cross-link to other databases or archives (eg. ... We recommend that authors of tables or catalogues identify their objects with the principal name, the celestial position plus possibly a name specific to the context (for example in a paper studying 3C sources use also the 3C name). ...

... SFIT is a general-purpose code designed to optimize theoretical stellar spectra to an observed spectrum. ... While the programme expects input from "stdio", it is more natural to save commands in a file (eg "sfit_input") and run the code simply by . ... If the spectra to be fitted have a filename "star_spectrum", then the best fit spectrum will be written out, together with the renormalized input spectrum, to a file called "star_spectrum.fit". ... sets up model spectrum grid (and for 2nd star) . ...
