  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 GAMIT/GLOBK Tutorial 11

  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 GAMIT/GLOBK Tutorial 11

  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) GAMIT/GLOBK Tutorial 11

  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 GAMIT/GLOBK Tutorial 11

  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 GAMIT/GLOBK Tutorial 11

  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 GAMIT/GLOBK Tutorial 11
