Relationship between the solar emission and the difference in ion production rate. The relationship between the solar emission and the difference in ion production rate between pre-flare and DTEC peak time calculated by GAIA with RUN-FS15. The difference in ion production rate is the difference between the pre-flare and the DTEC peak time, integrated over height. Data from points where the local time was around noon at the time of each flare event are used. The red triangles in each panel indicate the top five wavelengths at which the ion production rate was the greatest
