GHA:  Greenwich Hour Angle in degrees minutes and seconds.

Upper: TUC:  Time of upper culmination or upper meridian passage.  This is redundant in the sense that it is derived from and used in the same way as the GHA already tabulated.  It is provided for the benefit of a few users who are familiar with it's use in preference to GHA.  Note: this is the time at Greenwich, and as such must be corrected to the longitude of the observer as well as for the time zone of the observer.
