... SFIT is a general-purpose code designed to optimize theoretical stellar spectra to an observed spectrum. ... While the programme expects input from "stdio", it is more natural to save commands in a file (eg "sfit_input") and run the code simply by . ... If the spectra to be fitted have a filename "star_spectrum", then the best fit spectrum will be written out, together with the renormalized input spectrum, to a file called "star_spectrum.fit". ... sets up model spectrum grid (and for 2nd star) . ...

The English word "array" is translated into Swedish as "f lt" which is retranslated into English as "field". We may therefore perhaps use the word field either by mistake or as a suitable name of a specific array. A new feature of Fortran 90 is that you can work directly with a whole array or an array section without explicit (or implicit) DO -loops. ...
