Results of Absolutely Determing the Instrument Constant e and the Azimuth by Observing the Prime Vertical

After the test observations made in 1982,we improved the operating conditions of the instrument to increase in the accaracy and reliability of time records.The new instrument constant ￡ was obsolutely determined in 1983,the accuracy determined every time was ±0^s.0095 and we used the values of ε actually measured to calculate the absolute azimuth of the instrument with the accuracy determined every time being ±0^s.0125 and increasing by a factor of 2 as compared with 1982.
