:file:`sittbl.`
---------------

The :file:`sittbl.` contains options that can be set on a station-by-station basis.
The width of the table is variable, with the entries determined by the column headers present.
A complete version is available as :file:`~/gg/tables/sittbl.long`, but the short version shown below contains the only entries you are likely to change—the *a priori* station constraints to be applied in GAMIT to enhance ambiguity resolution and to obtain a solution that you can inspect visually (this assumes that your final solution will come from GLOBK).:

The 4-character site name must appear in the first four columns, the 12-character name is of arbitrary length beneath a blank header, and the coordinate constraints are free-format but must fall within the columns denoted by the header :content:`--COORD.CONSTR.--`.
The constraints are north, east, and up in meters.
