Results of the automatic triangulation. Top left: histogram of triangulated campfire heights. Top middle: scatter plot of height vs. the major axis length (the dotted line shows the H = L/2 relation, the red dots correspond to events triangulated manually in Sect. 3). Top right: scatter plot of height vs. the total intensity of a campfire. Bottom left: scatter plot of campfire shifts in latitude and longitude between the HRI_EUV and AIA 171 Å images. Bottom middle: scatter plot of campfire height vs. the longitude. Bottom right: scatter plot of the length of the shortest segment between the HRI_EUV and AIA 171 Å lines of sight for each campfire vs. its height. Most events lie below the dashed line indicating equal segment length and height.
