NAME

lvgchi - Calculates chi-square between data and model grid  

PERSON RESPONSIBLE

CATEGORIES

models  

DESCRIPTION

Calculates the chi-square values for input observational line temperatures against a grid of LVG models. The models are assumed to be generated by the program LVG.  

PARAMETERS

data
Name of file containing observational data in the following format: # of freqs
        freq1 freq2 freq3 ..... freqn
        temp1 err1 temp2 err2 temp3 err3 ..... tempn errn
        temp1 err1 temp2 err2 temp3 err3 ..... tempn errn
        ..... .... ..... .... ..... .... ..... ..... ....
where all data on a single line are assumed to apply to a single position. Each input line in the data file is assumed to be an independent position. All points must have measurements at all input frequencies. Maximum of 100 positions and 20 frequencies are allowed. No default.
model
Name of file containing model grid for chi-square calculation. This model grid should have been generated by LVG and may be either a 3-D or 4-D cube. No default.
out
Name of file for output chi-square cube. ONLY ONE data point may be done if out is specified.
log
Log file name. Default is to write to standard output.
