Computer Ephemeris. Tables for transformation from universal to sidereal time scale. Explanations.

This page contains three little tables headed Hours Minutes Seconds respectively. Each the table have two columns: first of them is input column where time in whole time units of universal time is given, and second of them is output column where hours:minutes:seconds of sidereal time is presented. To form result it is necessary to read from table 'hours' output number of hours:minutes:seconds when input number is number of universal time hours. Then repeat such the procedure for table 'minutes' for minutes of universal time and for table 'seconds' for seconds of universal time. After all three numbers must be added together to form correct result. If number of seconds isn't integer some little interpolation between neighbouring numbers is necessary.

Example: transform 02^h12^m22.00^s from universal to sidereal time.

Answer: 02^h as an input to the first table gives 02^h00^m19.71^s as an output, 12^m as input to the second table gives 12^m01.97^s as an output and 22.00^s as an input to the third table gives 22.06^s as an output. Summa of all these numbers is 02^h12^m43.74^s. This is the result.
