69. . 73. 02 The quantities D, P, L are given in the Astronomical Almanacs, the angle p as well as the distance r and the radius R are measured on the plate, for which purpose the direction of the daily parallel is plotted on the Image* In order to do this, two fine cross wires are placed in the photohelio- graph, before the plate, and the angular position of these is periodically sheeted by the method of transition of the Sun by these cross wires) the moments of contacts of the Sun's limb and ...the wires being determined* The position of the daily parallel can be also determined on these photographs, that contain two pootures of the Sun, taken at an interval of a few minutes, with a stationary tube* From the spherical triangle, that has the apices at the pole of the Sun, the detail and the end of the solar radius pointing toward the Earth, we find: sin u> = cos p sin D -4- sin p cos O cos (p C03(p sin I = 7i np sin (p-. P) ; cost cosp cosO sinp sin O cosfp P) . These formula are used to c pute (jp and I * The longitude A of the detail, in Carrlngton's system is found from the equation A = L+l.
