ccd_single¶
ccd_single is used to fit one or multiple SIP spectra using the Debye (or Cole-Cole) decomposition scheme. No smoothing regularization between the spectra is applied.
Command line options¶
INFO:root:Cole-Cole decomposition, no time regularization
Usage: ccd_single [options]
Options:
-h, --help show this help message and exit
-d FILE, --data_file=FILE
data file (default: data.dat)
--fmax=FLOAT Ignore frequencies above this value (default: None)
--fmin=FLOAT Ignore frequencies below this value (default: None)
--data_format=FORMAT Input data format, possible values are: rmag_rpha,
lnrmag_rpha, log10rmag_rpha, rmag_rpha, rre_rim
rre_rmim, cmag_cpha, cre_cim, cre_cmim. "r" stands for
resistance/resistivity, and "c" stands for
conductance/conductivity (default: rmag_rpha)
--data_weighting=SCHEME
Data weighting scheme to use. (default: re_vs_im)
--lambda=INT Use a fixed lambda (integer) (default: None)
-f FILE, --frequency_file=FILE
Frequency file (default: frequencies.dat)
--ignore=STRING Frequency ids to ignore, example:12,13,14. Starts with
index 0. (default: None)
--max_it=INT Maximum number of iterations (default: 20)
--norm=FLOAT Normalize lowest frequency real part to this value
(default: None)
-c INT, --nr_cores=INT
Numer of CPU cores to use (default: 1)
-n INT, --nr_terms=INT
Number of polarization terms per frequency decade
(default: 20)
-o DIR, --output=DIR Output directory (default: results)
--output_format=STRING
Output format(ascii| ascii_audit) (default:
ascii_audit)
-i, --plot_its Plot spectra of each iteration (default: False)
--plot_lcurve=INT Plot the l-curve for a selected iteration. WARNING:
This only plots the l-curve and does not use it in the
inversion process. Use -1 for last iteration.
(default: None)
--plot_reg_strength Plot regularization strengths of final iterations
(default: False)
-p, --plot Plot final iterations (default: False)
--silent Do not plot any logs to STDOUT (default: False)
--tausel=STRATEGY Tau selection strategy: data: Use data frequency
limits for tau selection data_ext (default): Extend
tau ranges by one frequency decade compared to the
'data' strategy. Factors can be set for the low and
high frequency by separating with a ',': LEFT,RIGHT,
e.g. '10,100' (default: data_ext)
--tmp Create the output in a temporary directory and later
move it later to its destination (default: False)
-v, --version Print version information (default: False)
Usage Examples¶
Note
Beware of the chargeability distribution at the frequency edges: Here the distribution is often dominated by the starting model due to low sensitivities. However it is advisable to add one frequency decade in values to the edges.
