Computer Ephemeris. Reduction quantities for Sidereal time. Explanations. Each row contains for the date specified at 0 h of Time Dynamical Sidereal: . sidereal julian day, . interval from date to mean epoch T m expressed in julian years, . reduction quantities A+A', B+B', C, D, (all in seconds of arc), E (in 0.0001s), A', B' (in 0.001). The same table, but for moments, expressed in Dynamical Time is to be found on 'Reduction. Dynamical time.' page. ...

... Restrictions ) are used. If specified form of output is EMP then astrometric equatorial coordinates are printed in the form usual for Ephemerides of Minor Planets, with formal precision of 0.01 minute of time in R.A. and 0.1 minute of arc in declination. ... It should be noted that the near-opposition ephemerides are not calculated for bodies/ points with numbers from –12 to 0 (in case they are included into task for computation of such ephemerides only their names are displayed in the results). ...

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. ...
