2. Line_width_variation_studies_by_EIS?

I'm getting first level data from zero level after usual reduction by 'eis_prep'. However, when i am fitting the lines by xcfit, i'm getting the spectrum slightly displaced from the wavelength values given in the data window. What error this will make in the calculations?. Secondly, can we get the accurate width variation ? , and can we use these datas for line-width variation studies ?

In response to your query we would need more information. Various work has been carried on line widths looking at the differences at different stages or positions of loops by Hara et al., and Doschek et al (both been submitted), so clearly line widths can be measured.What variation are you referring to?
