The volume emission measure EM(V) of the arch systems of the inner corona, not immediately associated with developed active regions, has been determined by analyzing the pictures of the green corona. It was found that the EM(V)-values of these systems are substantially lower than those obtained from X-ray data for the active regions, and this fact should be taken into account in interpreting extraatmospheric observations. The combined investigation of data on the radiation of the corona in the green line and in the continuum enables one to determine the total extension of the radiating matter, (0.5-1) x 10 to the 10th cm, as well as the density in the separate arches, of about 1.5 x 10 to the 9th/cu cm. It is assumed that matter exists between the arches with a density of not more than 10 to the 8th/cu cm.
