The annual files (1939-1993) contain the green coronal emission line 530.3 nm observations. The coronal intensities are given in millionths of intensity of the solar disk (coronal units) and converted to the photometrical scale of Lomnicky Stit Station at a height of 40" above the solar limb. Several stations were used in this database with Lomnicky Peak being the primary station since 1965. Reference: Rybansky, et al, 1994, Solar Physics 152, p 153-159.
