These include the data files shown at the beginning of this section, but also the orbit, clock, and coordinate files created during the processing. The primary orbital information for GAMIT is the (short, ascii) g-file (e.g., :file:`gigg0.034` where the :file:`f` for final in the :option:`-orbt` option has been replaced by :file:`g` to indicate GPS), which contains for each satellite the values of position and velocity at a particular epoch (usually 12:00 on the day being processed) and coefficients of the 9-component solar radiation-pressure model. These 16 parameters are sufficient for :program:`arc` to generate a tabular ephemeris (binary t-file, e.g., :file:`tigsg0.034`) for model to use in computing the theoretical value of the observations. In normal processing, the g-file is created by :program:`sh_gamit` (invoking :program:`sh_sp3fit`) in the :file:`igs/` directory by fitting :program:`arc`'s model to an ascii tabular ephemeris (in the IGS SP3 format) from an external source. :program:`sh_gamit` then copies the g-file to the :file:`gfiles/` directory and creates a link from the day directory to the file in :file:`gfiles/`. This complicated procedure is useful for two reasons: 1) GAMIT requires partial derivatives of the orbital position with respect to the initial parameters in order to estimate these parameters, and these are not available on the SP3 file; 2) the :file:`igs/` and/or :file:`gfiles/` directories can be used to create multiday orbits for processing pre-IGS data. The satellite clock file (e.g., :file:`jcodr0.034` or :file:`jbrdc0.034`) and receiver clock files (e.g., :file:`kblyt0.034`, :file:`iscal0.034`) all exist solely within the day directory. A description of each of these files may be found in Chapters 1 and 2 of the `GAMIT Reference Manual `_. The main coordinate file for the survey is named :file:`lfile.` and kept in the project :file:`tables/` directory. When :program:`sh_gamit` runs it makes a day-specific link, e.g. :file:`lscal0.034` within each day directory, where updates are made by after each of the two solutions and given the names, e.g., :file:`lscala.034` and :file:`lscalb.034`. We discuss in :numref:`intro_proc_flow` the rules for updating :file:`../tables/lfile.`.”h]”(hX The third set of files comprises those that are day-specific. These include the data files shown at the beginning of this section, but also the orbit, clock, and coordinate files created during the processing.
