Stadia observation yielded the following results: vertical angle, +13°20': top stadia hair reading, 4.500 m, and lower stadia hair readin 3.250 m, respectively. The rod reading was taken at A, which is 3.875 m above the stadia point, and B, which is 1.620 m above the instrument station. The instrument constant is 0.381 m, and the stadia interval factor is 99.5. What will be the horizontal distance between the instrument station and the stadia point?
