Remarks
It is required for a driver to calculate this from the system clock if the telescope
has no accessible source of sidereal time. Local Apparent Sidereal Time is the sidereal
time used for pointing telescopes, and thus must be calculated from the Greenwich Mean
Sidereal time, longitude, nutation in longitude and true ecliptic obliquity.
