hfs_file

Back to the main HfS page

hfs_file is a batch procedure to fit the hyperfine structure of the same transition (and a single velocity component) for a set of data files. The fit procedure is the same as that of hfs_fit, but it is not interactive.

Input

• <file_list>.par: parameter file with the following information:
  1. Transition name (e.g. "NH3(1,1)", "C18O(1-0)") or identification number (its position in the hfs_transitions.dat file).
  2. Iteration parameters: Nksample, Final_Range.
  3. and following lines: list of files, one file per line

The file can be given as an argument to hfs_file:

$ hfs_file <file_list>.par

Example of input <file_list>.par:

Output

• hfs_file.log: log file with the details of the fitting process for all the files in <file_list>.par.
• <file_list>.out: ASCII file with the values of the parameters fitted for each file of the list. The first lines beginning with "!" are the header and give information about the transition and the column headers. The following lines have 10 columns: Δv, Error, v_LSR, Error, Aτ_m, Error, τ_m, Error, Rms, File name. The file is readable by GREG.
• <file_list>.ps: PostScript file with plots of the data, the components fitted, and the residual, for all files in the list.
• <file_#>.synt: An ASCII file for each file in <file_list>.par, with the synthesized spectrum. The file has a header (lines beginning with "!") with the values of the parameters of the fitted spectrum. The file is readable by GREG.
