2. Generating Time Series
Glred produces a single file containing position estimates for each day
Script sh_plotcrd extracts position estmates from this file and uses GMT to produces a postscript time series for each site
Sh_plotcrd invokes programs ensum and multibase, and script sh_baseline which produce intermediatefiles
With sh_glred, the glred outputs are separate files but the intermediate files are the same

3. sh_plotcrd
sh_plotcrd reads an input solution file and plots the times series with GMT. Basic format is sh_plotcrd –s <span> -f <files>
where <span> is ‘long’ or ‘short’ to control whether x-axis is days or years, and whether velocities are removed
Output is postscript files with names of the form psbase.<site> (North, East, Up components are all on the one plot).
Other options available

4. Ensum input and files
ensum is used to extract station coordinates from the repeatability runs
ensum <options> <summary_file> <values_values> <Input solution files ..>
options: Main option is the minimum number of values to be used in computing RMS (for repeatability this is 2)
Summary file is name of file which contains a summary of the repeatability by site and component (NEU)
Values file is the actual time series of results
Input solution files is a list of .org or .prt files or values files from previous runs (must start with va)

5. multibase
multibase extracts individual time series from a values files and generates a series of files for individual sites and components of the form mb_<site>.dat[123] where 1 is North, 2 is East and 3 is Up
Time can be in day-of-year or years depending on how long the time series is

6. sh_baseline
sh_baseline plots the times series with GMT and generates postscript files with names of the form psbase.<site> (North, East, Up components are all on the one plot).
sh_baseline -help gives all the options

7. Velocity plots
sh_plotvel extracts velocities from a prt/org file and creates GMT plots sh_plotvel –f <file> -s <site> where <file> is a glorb prt/org file and <site> is a reference site (optional)
Many other options to customize plots
