Resumen:
Solar rotational tomography (SRT) allows reconstruction of the three-dimensional (3D) distribution of the coronal electron density $N_e$. Using white light images the electron density results are of an absolute nature. Using Extreme Ultraviolet (EUV) images the results depend on the iron coronal abundance [Fe] and the coronal density irregularity factor X≡/², where indicates the average over the tomographic voxel. Applying both methodologies independently allows determination of $X$ assuming values for [Fe]. We develop a new tomographic technique that jointly exploits optical and EUV data, that will allow determination of these parameters in a joint manner along with other fundamental coronal parameters. In this work we describe the technique, dubbed Multi Instrument Tomography, currently under development.
