In order to calculate the line profile of a given absorption line for atomic species Z with a wavelength LAMBDA (in Angstroms) and a microturbulent velocity VT (in km/s). ... mode . ... 1) The input model may contain more than one model (i.e. it may be an entire grid of models). Spectrum will cycle through this grid NMOD times, omitting NSKIP-1 models from the . ... However, the input data following MODE must be repeated NMOD times in order to obtain equivalent results for each model in the grid. ...

Inverted TRACE images at 195 illustrating development of the EUV post-eruption arcade with the well-organized loop, two-ribbon, and spine structures. Note that the exposures have been rescaled to the same peak intensity to show the evolution of the bright elements. The field of view is 220.5 by 182 Mm. Back to paper .

... The calibration of astrophysical spectra in wavelength based on calibration lamp data suffers from different kinds of uncertainties. Besides inaccuracies in the observational phase, common data reduction practice adds ``pixelation'' errors, due to the fact that the centering method does not use the correct PSF. These model mismatch errors depend, for a given feature, on the sub-pixel location of the line center (David & Verschueren, private communication). ...
