The input is not fixed width and is validated when loaded. The validation checks for correct number of parameters, correct numerical format and correct filter names. The offset command is an absolute TCS offset command in TPLANE mode. Both parameters are in arc-seconds with a maximum allowed value that is set in the configuration file:
<tcs-dither-limit>900.0</tcs-dither-limit>
If a pattern needs to be repeated, the loop count can be increased. Other wise a pattern will run only once. The initial action is to "Load Pattern File" which will present a dialog box for sleeking the input file. The default extension is *.txt but the dialog box allows selection of other types even though they are dimmed. The "Execute" button will be enabled after the input has been processed and validated.
