Galaxy Rotation Velocity Fittings

The folder named data-C-galaxies input contains the input data reported in the Sofue's database in Excel format for the 291 galaxies of this series, while the corresponding data-C-galaxies-output files present the detailed fitting results for each galaxy of the C-Series.

The first plot is the global dispersion curve. The EXCEL file following this spread curve summarizes the fitting parameters, the estimated mass, the maximal velocity and the SNR results obtained for the individual best fitting plots for each galaxy. These plots are successively presented after the EXCEL files.

Similarly, the files named data-P-galaxies input and data-P-galaxies-output as well as data-S-galaxies input and data-S-galaxies-output report the input data and the best fitting results of the 31 galaxies of the P-Series and of the 229 galaxies of the S-Series respectively.

As seen in the last lines of the EXCEL files, overall, the mean SNR and its standard deviation is 25.2 (3.8) dB for the C-series, 23.6 (5.2) dB for the P-series and 22.1 (5.9) for the S-series, which can be considered as very good for a two-parameter fitting.
