| + | One thing to check for is the presence of clock breaks. This is best done using aedit with the command "plot mbd". You may need to set the y-scale to see things clearly with "yscale -0.05 0.05" (scale in microseconds, so this gives a \pm 50 ns window) | ||
| + | |||
| + | If you are producing a tarball to send to Washington, you can considerably reduce the size of the file by excluding the baseband data when using tar. To do this, use this command from the data directory: | ||
| + | |||
| + | tar --exclude='*..*' -cvf aust10.tar aust10 | ||
| + | |||
| + | This will reduce the size of the gzipped tarball from by a factor of ~10-20 (Expect sizes of a few 100 MBs). | ||
| + | |||
| + | If you're creating a database yourself, leave the baseband data alone. You can now proceed to the next step using calc/solve (installed on ops7). | ||
