Abstract
First, I drew the contours of constant probability density of Decca fixes in the adjacent waters of Hokkaido and Kyushu, using the "probaaility density formulae." Secondly, by comparing these of Loran fixes with the abovementioned contours, I tried to make a practical chart of Loran and Decca coverages, with which navigators could select the appropriate chain and pair of the Decca system or the triplet of Loran stations to obtain the most accurate fix in the ditto waters in daytime and at night.
