... There are compelling reasons for the pulsar community to utilise a standard data storage format. For example, standardisation of file formats significantly decreases the amount of effort required to integrate new instruments into the analysis chain. ... Accordingly, we have defined PSRFITS as a standard FITS-based format for pulsar data files. ... For example, the first line of Processing History HDU contains information about the data acquisition program and the initial structure of the file. ...

Programs to generate color spectra ================================== These programs were developed to produce realistic color spectra from digital data. ... The distribution here contains the original source code for colorspec and solar in C, and a version of solar written in Fortran. ... It will produce a color spectrum of any digital spectrum. ... The 800x50 image solarflux.ppm was generated by colorspec and the file fluxatlas.dat, a reformatted NSO Solar Flux Atlas in the data directory. ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...

In this chapter we will consider two very simple but useful Web agents that I have written on Actor Prolog for my own needs. ... Let us start the Web agent. Fig. ... Start of the Web agent. The Context diagram consists of three blocks: "Logic Programming Sites", "Edit", and "Check". ... Some Web sites that are linked with the logic programming and Prolog are listed in the pulldown list (these addresses are transferred to the "Edit" block from the "Logic Programming Sites" block). ...

Investigations of the ionospheric response to strong magnetics storms which are usual for our latitudes, are of great interest. ... In the figure, we present ionospheric parameter dynamics during three perturbed days in July 2000. ...

... First, we computed the mean errors of orbit parameters on the assumption of the linear connection of them with observation errors and then we compared obtained estimates with those resulting from the assumption of the nonlinearity of this connection. Secondly, we correlate orbital parameters and their errors obtained by the method of the least modulus with those obtained by the least-squares method. ...
