Both procedures yield the same hour angle, apart from negligible differences which are of the order of one milliarcsecond or below.
WebGreenwich Apparent Sidereal Time (GAST) is the hour angle of the vernal equinox at the prime meridian at Greenwich, England. Local Sidereal Time at any locality differs from the Greenwich Sidereal Time value of the same moment, by an amount that depends on the longitude of the locality. WebthGMST = siderealTime(utcJD, dUT1, dAT) calculates mean sidereal time at a specific Coordinated Universal Time (UTC) at a higher precision using Earth orientation …
WebThe difference between mean and apparent solar time is known as the equation of time. This is usually expressed as a correction, never exceeding 16 minutes, that is added to or subtracted from apparent solar time to determine mean solar time.
