... With all relevant information being available in an Observation Summary Table, this can be accomplished by supplying a suitable logical expression to the general purpose command SELECT/TABLE. ... This interface enables the user to interactively enter constraints on the existing fields of the OST. ... The command CREATE/CRULE susi_ost bias . ... The user should then, for instance, formulate a rule for classifying BIAS exposures by entering constraints on columns of the OST (Table ). ... BIAS*".AND.: ...

Next: Interrupts and Signals Up: Piping in a C program Previous: popen() - Formatted Piping . int pipe(int fd[2]) - creates a pipe and returns two file descriptors, fd[0], fd[1] . fd[0] is opened for reading, fd[1] for writing. pipe() returns 0 on success, -1 on failure and sets errno accordingly. ... Pipes opened with pipe() should be closed with close(int fd) . ... An example of piping in a C program is plot.c and subroutines and is detailed in Appendix . ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

... the data are described accurately enough to allow an unambiguous interpretation of the data, as well as a comprehension of the context in which the data were acquired and/or processed; a single ascii file, named ReadMe , is designed for this role. the data are in a format which allows their usage by tools currently in usage in our discipline -- normally flat ascii files ; other formats can be accepted, but are converted into flat files. ... How to prepare the Data files . ... How to deposit the data...
