EIS_AUTO_FIT and SPEC_GAUSS_EIS: Gaussian fitting routines for the Hinode/EIS mission
Description
The EUV Imaging Spectrometer (EIS) was launched aboard the Hinode spacecraft in 2006. EIS observes the solar atmosphere in the two EUV channels 170-212 Angstroms and 246-292 Angstroms. A basic requirement for any emission line spectroscopy mission is a set of software suitable for fitting Gaussians to lines in order to derive intensity, velocity and line widths. This document describes a set of IDL routines available for the Hinode/EIS mission that are intended to cover most situations encountered by EIS observers.
