... fit_opt] [mean_opt] . This command determines the characteristics (position, width, height) of each selected stellar object through a non--linear best fit to the data. ... Besides the best fit, FIT/ROMAFOT also computes the quality of the fit by the test and the semi--interquartile interval for each individual object. ... This happens when the command is requested to fit a window with several objects and when one or more of these falls into the category ``NO CONVERGENCY''. ...

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. ...

... To run the <LAYER> version of the example, select: flower.htm . ... However, if the page had several layers with absolute positions, and you wanted to place another layer in a relative position to one of the existing layers, you could use inline JavaScript to calculate the value for LEFT or TOP . ... In this example, there is really no need to use inline JavaScript to position the last flower layer, since you could just let the TOP value default to its natural value, as in the other flower layers. ...
