All the observations have been made with the use of a double-arm spectrograph which provides spectra with a wide wavelength coverage, from 3200 to 10500 Åfor the WHT data and 3400 to 10400 Åfor the CAHA data, of exactly the same region of a given galaxy. These spectral ranges include the [Oii]λλ 3727,29 Å lines, the [Siii]λλ 9069,9532 Å doublet as well as various weak auroral lines such as [Oiii]λ4363 Å and [Siii]λ6312 Å. We propose a methodology to perform a self-consistent analysis of the physical properties of the emitting gas of Hii galaxies adequate to the data that can be obtained with the XXI century technology. This methodology requires the production and calibration of empirical relations between the different line temperatures that should superseed currently used ones based on ve...
