STAR*NET V6 - Circe

Chapter 4 OPTIONS
4.1 Overview
STAR*NET maintains a list of settings for each job called “Project Options.” Most of
these options are settings and values that control how STAR*NET processes an
adjustment, and they are set by the user in dialogs discussed on the following pages.
Other stored settings relate to the contents of plotting diagrams and DXF exports.
STAR*NET stores the options for a project by creating a file named “PROJECT.PRJ,”
where “PROJECT” is the name of the project, for example, SouthPark.prj. All project
specific options are saved in this file. If you open an existing project at a later date, those
options automatically load and will remain in effect until you change them.
A special “default options” file is located in the directory you installed STAR*NET. It is
referred to as the Company options file; its real name is STAR6.DEF. It is automatically
created when run STAR*NET for the first time after installing the program. It initially
contains a set of generic defaults you should change to settings more typical of your
projects. These typical option settings will be applied automatically to any new project.
Setting the Company options will be discussed later in this chapter.
When you have a single project that requires several different weighting schemes
(different instruments used, or combining an old survey with a new survey), you can
store several sets of instrument standard error values in a special “Instrument Library”.
This information may be saved in the Company options file for use in any project, or in
the project’s own “PRJ” file for use only by that project. Using special “inline” codes,
these settings can be referenced anywhere in the data files to change the weighting
scheme of subsequent observations. Using the Instrument Library is discussed in detail
later in this chapter.
