Next: Stellar models Up: Introduction Previous: Photometry Contents . In a hierarchical stellar system, the separation between two neighboring stars is always much smaller than the separation of this pair from the next companion in the system, be it another pair or a single star. ... They are also numerically easier to handle than non-hierarchical systems, since each pair can be described with the standard orbital parameters, and each star with a small number of physical parameters. ...

... The regions can be specified via the outunit parameter in either of two projection-plane coordinate systems, namely `detxy' and `xy'. ... The first choice corresponds to columns DETX and DETY of the standard XMM EPIC event list, the second to columns X and Y . ... This information is obtained from keywords in the header of the supplied event list. ... If outunit is given as `detxy' and if the supplied source list is a standard XMM EPIC product then in principle the event list is unnecessary. ...

... To use system calls and library functions in a C program we simply call the appropriate C function (Appendix ). We have already met some system calls when dealing with low level I O - open(), creat(), read(), write() and close() are examples. ... All math functions such as sin(), cos(), sqrt() and random number generators - random(), seed(), lrand48(), drand48() etc. are standard math library functions. NOTE: most standard library functions will use system calls within them. ...

... Coordinate system . It is necessary to specify the coordinate system for the drilling of plug-plates so that the drilling file (currently named plPlugMap), plate drilling, cartridge, rotator wrap and the rotator itself are compatible. ... The TCC rotator angle (object system) is defined to be 0 degrees for this orientation. ... Thus, the rotator angle gives the conventional astronomical position angle on the sky of the y axis (although Russell won't acknowledge this necessarily). ...
