Number of Continuum bins (ncn2)

New in version 2.2 is the option to control the number of continuum bins. Continuum bins are logarithmically spaced between 0.1 eV and 40 keV, and are calculated according to:


\begin{displaymath}\Delta\varepsilon/\varepsilon=(40 {\rm keV}/0.1 {\rm eV})^{1/(0.49 {\rm ncn2})}\end{displaymath}

ncn2 must be in the range between 999 and 999999. The higher value is appropriate for use in modeling X-ray grating spectra. The lower value is appropriate for models where only integrated line luminosities or ionization fractions are desired. Execution time scales approximately proportionately to ncn2.
