The CHIANTI database has been compared with observed spectra in the 1-50 Å wavelength range in order to test for correctness and completeness. We have compiled a list of observed lines from high resolution solar spectra for this comparison, in a manner similar to Paper I. This compiled list includes observations from:

The numbers between 1 and 20 refer to the reference key provided in the last column of Table 5. Aside from the spectra of Widing and Sandlin 1968, all of the spectra were observed during solar flares. We have developed a composite of these spectra by combining all of the observations within a narrow wavelength interval.
Because of the relatively low resolution of the X-ray spectra compiled by Doschek 1972, we have not included all of these observed wavelengths.

The results of this analysis are presented in Table 5. Whenever solar observations were available, the average of the observed wavelengths for each single spectral line feature is given in the first column of Table 5 (the last column provides a key to the reference to the observations). If there are CHIANTI predicted lines associated with the observed line, they are listed, with their CHIANTI wavelength (in second column), their identification (third and fourth column), and intensity of the line (fifth column). A blank first column indicates multiple strong lines that can be associated with the observed wavelength. Note that only the brightest lines contributing to each blend are shown. A `.....' in the first column indicates a strong spectral line that is expected on the basis of the CHIANTI computed spectra that has not apparently been observed.
The intensities of the lines in the CHIANTI database have been calculated as in Paper I, using a differential emission measure (DEM) of a solar flare between 3 x 10⁴ and 2 x 10⁷K is taken from Dere and Cook (1979) this time enhanced and extrapolated to 10⁸K in order to reproduce the lines at the shortest wavelengths. The calculations of the line intensities assume the solar elemental abundances of Allen (1973), the ionization equilibria of Arnaud and Raymond (1992) for iron ions, Arnaud and Rothenflug (1985) for the other abundant ions and Landini and Monsignori Fossi (1991) for the minor ions. The line intensities are expressed in erg cm^-2 s^-1 str^-1.
If there are no bright lines predicted by CHIANTI, associated with the observed one, a `missing' line is listed in the Table. This line can be recognised by the absence of a predicted intensity (i.e. a `...' in the intensity column). Wavelengths and identifications are those given by Kelly (1987).
The CHIANTI database predicts many more lines than are listed in Table 5 but we have not included lines below a threshold value suggested by the intensities of the lines that have been observed. The CHIANTI database also predicts the presence of many lines that apparently have not been observed yet. Some of these lines are from energy levels that do not have observed values, and are not included in the Table.

We stress that the intensity values in the Table should only be used as a guide to the identification and the problem of blending and should be used in a relative sense. Some identifications should be considered simply coincidental if the expected intensity is relatively low.
