Greenwich mean and apparent sidereal time
In the past, time was measured by observing stars with instruments such as photographic zenith tubes and Danjon astrolabes, and the passage of stars across defined lines would be timed with the observatory clock. Then, using the right ascension of the stars from a star catalog, the time when the star should have passed through the meridian of the observatory was computed, and a co… WebMay 29, 2012 · The output matrix will be in the same size as the input matrix. Warning: Use caution when using GAST as a substitute for Greenwich Mean Sidereal Time (GMST). To run JD2GAST, use the following code sequence: GAST = JD2GAST(JD); Where: JD is the Julian Date input (days) GAST is the resulting Greenwich Apparent Sidereal Time …

Local Sidereal Time at any locality differs from the Greenwich Sidereal Time value of the same moment, by an amount that is proportional to the longitude of the locality.
