(1) Image of a meteor on a 3^∘×3^∘ frame (𝐹(𝑖,𝑗)). (2) Extraction map. Black shade shows the points with 𝐹(𝑖,𝑗)>𝑛_𝜎⋅Σ(𝑖,𝑗); white shade indicates the points included into the object under study. Grey shade indicates the background. (3) Background map—(Bg(𝑖,𝑗)) (bottom left). (4) More exact map of a background use SExtractor background estimation algorithm [8].
