Next: Inspection of results Up: *fit* - Fit Data Previous: Verbose Mode . If the number of net counts for a source is less than it is impractical to fit the data in all 34 energy bits. However, if the flux is required, then a fit must be performed first. ... Fit will then calculate the normalization of the model and xflux can be used to determine the flux and luminosity of the source from the best fit model. xs> fit rebin=yes . ...

... Formulas are very similar to equations. Consider for now only equations with one unknown variable , denoted by some letter, which can be x but can also be different. An equation is an equality between two mathematical expressions containing the unknown number (maybe in several places), as well as other numbers which are known. ... For instance--if you multiply two sides of a formula by the same number, the result is still a valid formula, even if what you multiply contains unknown numbers. ...
