Basic Information on radchi

Task: radchi
Purpose: Calculates chi-square between data and a microturbulent model.
Categories: models

Calculates the chi-square values for input observational line
temperatures against a microturbulent model. The models are
assumed to be generated by the program RADSPH.

Key: data
Name of file containing observational data in the following
format: radial-position freq line-temp temp-error
        radial-position freq line-temp temp-error
        ............... .... ......... ..........
Maximum of 200 data points.
No default.

Key: model
Name of file containing model for chi-square calculation.
This model grid should have been generated by RADSPH.
No default.

Key: log
Log file name. Default is to write to standard output.
