. Computer Ephemeris. Sidereal time. Explanations. Each row contains at 0h of Universal time: month, day, real sidereal time (hours, minutes, seconds), mean sidereal time (only seconds, as a rule, hours and minutes are the same as in real time) and nutation in right ascension: long periodic (with periods greater than 35 days), and then short periodic (periods less than 35 days). Standard IAU 1980 nutation theory is used.

... LST causes SCHED to assume that all input times are in local sidereal time. ... Otherwise, a station name can be given to allow scheduling in lst for some other station. When LST is specified, there are two ways to specify the date. DAY can be used to specify the (modified?) local sidereal day number as found on the VLA monthly schedules. ... In this case, SCHED will figure out when on that calendar day the local sidereal time specified for a scan occurs. ... Default: Not used if not given. ...
