1. Introduction

The CHIANTI database, described in Paper I, aims to provide solar and stellar researchers with access to the best available atomic data from which the emission lines of all the major atomic species can be studied using IDL routines. An important part of the CHIANTI project is to check the accuracy of the atomic data by comparing the observed intensities of emission lines recorded by various rocket and satellite missions with the intensities predicted by CHIANTI. The first of such comparisons is presented here with regard to the recently published active region spectrum of Thomas & Neupert (1994). Comparisons with Extreme Ultra-Violet Explorer (EUVE) and Solar and Heliospheric Observatory (SOHO) data will follow.

The details of the SERTS-89 spectrum and the method of analysis are presented below, followed by the detailed comparison of each ion with theory.
