- W2371437864 abstract "The adopted longitude of Zi-Ka-Wei Observatory Time Base should take a correction +37 ms, according to the astronomical longitude determination during July 1957 to December 1959. This correction is measured between Greenwich and Zi-Ka-Wi,both referred to the weighted mean observatory which is formed by 42 time stations through out the World. For the establishment of the weighted mean observatory,the following procedure is taken. First,the astronomical determination of UT2 obtained at each time station are reduced to the Soviet Standard Time System.The data of Zi,Pa,G,To,Ira,Irm,Kh,La, Lm,Ma,Mg,Mm,MP,Nk,Nm,Pr,Pt,Pu,Rg,Ta etc.(20 stations) are discussed according to the different observers and instruments used.For visual instruments,we considered the personal error of each observer referred,to the weighted mean observer.After eliminating the personal error thus obtained,we combined the time observations anew,and formed the monthly mean of each instru- ment,or the mean of some twenty series observations as in the case of the four stations Zi,Pa,G, To.If the number of instruments used at a station was more than one,a similar combining process among different instruments should be made,Afterward,the monthly deviations of UT2 determina- tion of each station as referred to the System which are denoted by Di were calculated and compiled in Table 11. For the remaining 22 stations,we reduce the Pi of each station to the System,after forming the five-day mean of these values (rejecting the data if there were no observa- tion made during the five days),the monthly mean of the five-day mean values are taken as the Di of the station concerned and again listed in Table 11. Secondly,we calculated the mean value of Di of each station,the results are shown in Table 12, where n denotes the number of working months;D,the mean of Di;E_D, are the mean-square error of and Di respctively.The weight P is asigned to each station according to E_D and technical conditions.Weighted mean D_* repressents the mean departure of the System from the weighted mean observatory during 30 months,δ is the departure of each station to the weighted mean observatory and ΔL is the correction to the adopted longitude." @default.
