This directory contains the following overview plots for all MGEX
stations for the last 30 days:

ep30.png: Shows the number of 30s (+- 0.01s) epochs in the daily RINEX
          files. This is an indicator for the completeness of the
          files.

ll0.png:  Shows for each file the number of observations, for which
          the loss of lock (LL) bit 0 was set (lost lock between
          previous and current observation, cycle slip possible, for
          phase observations only).

ll1.png:  Shows for each file the number of observations, for which
          the LL bit 1 was set. For RINEX 2 files this means: Opposite
          wavelength factor to the one defined for the satellite by a
          previous WAVELENGTH FACT L1/2 line or opposite to the
          default. For RINEX 3 files: Half-cycle ambiguity/slip
          possible. Software not capable of handling half cycles
          should skip this observation.

ll2.png:  Shows for each file the number of observations, for which
          the LL bit 2 was set. For GPS, this means, that the
          observation was obtained under antispoofing (RINEX 2), for
          Galileo, that an MBOC-modulated signal was tracked.

sys?.png: Where ? is G (GPS), R (GLONASS), E (Galileo), S (SBAS),
          J (QZSS) or C (Beidou). These plots show the number of
          tracked satellites of the corresponding satellite system.

In the plots, the numbers of epochs, observations and satellites are
coded using colors. White areas mean, that no data/files are available.
