WebbThe average optical density (AOD) is merely IOD divided by area [8–11]. The total number of object pixels is the simplest measure of an object’s area. Thus the AOD of an M × N image can be calculated by (8.39) where A = M × N is the area of the image. Webb29 aug. 2024 · The electron density can be k m − 3, m − 3, c m − 3, there's no convention. The product of a density and an area is going to be a l e n g t h − 1. The integral with respect to conformal time is going to be s l e n g t h − 1. Normally, the choice of a unit wouldn't matter, but this length is used as an exponent in the Visibility Function Webbunit, and universal gas constant.
