Sample No 0-4: RINEX observation data, daily metadata as graphics, station lifetime.

Graphics key: Window Length = hours recorded from first to last epoch; Actual / Max. Obs (%) [red], with number of GPS satellites also shown [blue]; MP1 = multipath f1, MP2 = multipath f2; Slips per 1000 Obs. = number of cycle slips per 1,000 observations.
