| - | === Using EIS fitting software for SPICE === | + | For IDL Gaussian fitting software, please check: **[[data:line_fitting_idl|IDL software for emission line fitting]]**. |

| - | The routine spice\_getwindata returns a "windata" structure in a form compatible with the eis\_auto\_fit suite of routines for Hinode/EIS. Further information on these routines is given in [[https://doi.org/10.5281/zenodo.6339584 | + | |
| - | |EIS Software Note 15]]. The mask spectra fitting routines (Case 2 in the document) do not currently work with SPICE, however. | + | |
| - | The EIS software enable a number of operations to be performed on windata structures, as described in [[https://sohoftp.nascom.nasa.gov/solarsoft/hinode/eis/doc/eis_notes/21_WINDATA/eis_swnote_21.pdf|EIS Software Note 21]]. For example, eis\_bin\_windata allows spatial binning of the rasters. | + | Fitting in Python can be done with any fitting library, including [[https://docs.astropy.org/en/stable/modeling/|astropy.modelling]]. From astropy 7.0, there is a user-friendly way of doing the fitting in parallel ([[https://github.com/aperiosoftware/parallel-modeling-examples/blob/main/spice/Final_Tutorial.ipynb|tutorial]] by Stuart Mumford). |
| - | If you have problems running the EIS software on SPICE data, please contact [[https://science.gsfc.nasa.gov/sed/bio/peter.r.young|Dr. Peter Young]]. | + | This is used by the [[https://pypi.org/project/pycfit/|PyCFIT]] library, which provides a GUI for fitting the different components. |
