Introduction

Diagnostic dot files specify geometric and auxiliary information about each diagnostic. Parsing of a diagnostic dot file begins by searching for a valid keyword. All lines before a valid keyword is reached are ignored allowing for comments and other information to be inserted in the file. Once a keyword is reached, the parsing becomes strict. The diagnostic description format is dependant on the specific keyword. All diagnostic dot files must end with an end_of_file keyword.

This document contains information about the sxrem ratio point specifications. Points are specified in a structured text file. This file is read in by the v3fit_input::sxrem_ratio_dot_filename variable of the name list input file. Points are specified as a verticies in either meters or radians.

Keywords

sxrem_ratio_XYZ	A sxrem ratio point specified in Cartesian coordinates measuring electron temperature.
sxrem_ratio_RPhiDegZ	A sxrem ratio point specified in Cylindrical coordinates measuring electron temperature.

Point Specification

All thomson scattering points are specified in the following manner. Indices a specified such that the order defines the ratio as index1/index2.

key_word
