The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

... It uses the transformation parameters computed by the command ASTROMET/TRANSFORM . ... ASTROMET/COMPUTE computes the RA,Dec coordinates from X,Y coordinates directly from the transformation parameters, while it obtains X,Y from the RA,Dec ones in an iterative manner. Also note that the equinox of the computed coordinates is the same as the standard star catalogue (which is NOT necessarily the same as its epoch) and is 2000.0 in case the PPM catalogue is used. ...

One of these TF methods, the short-time Fourier transform (STFT), has been used extensively for analyzing speech, music, and other non-stationary signals. ... Another time-frequency representation (which might more appropriately be called a time-scale representation) is the well-known wavelet transformheil-walnut,mallat:theory,daubechies:transform,strangwavelets. ...

The technical memorandum: Time and Time Interval Measurement with Application to Computer and Network Performance Evaluation (PostScript) describes a number of techniques for conducting experiments typical of computer network and transmission systems engineering. ... The usual data collected during a performance run of some experiment might include time offsets, time delays, frequency offsets and various error statistics. ...

... Avg: the average value of the spectra (maybe throwing out some channels at the edges). <>:average over the spectra (throwing out points at the edges if you want). gCal(f) :- frequency dependence of the tabulated cal values. ... calInK(Avg): Scaler cal value averaged over the band. calOffSpc(Avg): cal off value averaged over the band (in spectrometer counts) . ... cntsToK(avg) = calInK(Avg) / (calDif_cnts(Avg)) .
